Philippe Van Nedervelde's E-spaces 3D Art Studio created Nanobots replacing neurons (nerve cells). This a still image of HD animation, depicting robots in the brain, from the transhumanist documentary Beyond Man (2005).

Although imaginary, current developments like MIT's nano neuro knitting experiment in which peptide nanofiber scaffolding was used to repair brain tissue in a hamster (article in PNAS) make it prescient.

Van Nedervelde's art is part of NANO, a virtual exhibit curated by transhumanist visionary Natasha Vita-More to showcase nanotech art by artists from a number of disciplines, including the multitalented Anders Sandberg. He's a computational neuroscientist and research associate at Oxford's Future of Humanity Institute.

Spontaneous mentalizing during an interactive real world task: An fMRI study.

Neuropsychologia. 2006 May 8;

Authors: Spiers HJ, Maguire EA

There are moments in everyday life when we need to consider the thoughts and intentions of other individuals in order to act in a socially appropriate manner. Most of this mentalizing occurs spontaneously as we go about our business in the complexity of the real world. As such, studying the neural basis of spontaneous mentalizing has been virtually impossible. Here we devised a means to achieve this by employing a unique combination of functional magnetic resonance imaging (fMRI), a detailed and interactive virtual reality simulation of a bustling familiar city, and a retrospective verbal report protocol. We were able to provide insights into the content of spontaneous mentalizing events and identify the brain regions that underlie them. We found increased activity in a number of regions, namely the right posterior superior temporal sulcus, the medial prefrontal cortex and the right temporal pole associated with spontaneous mentalizing. Furthermore, we observed the right posterior superior temporal sulcus to be consistently active during several different subtypes of mentalizing events. By contrast, medial prefrontal cortex seemed to be particularly involved in thinking about agents that were visible in the environment. Our findings show that it is possible to investigate the neural basis of mentalizing in a manner closer to its true context, the real world, opening up intriguing possibilities for making comparisons with those who have mentalizing problems.

Chang Soo LEE and HyeJoo Lee have developed MoBeeline, a system that allows people to send data about a user's emotions to another's clothes via SMS.

From the project's web site:

MoBeeline is a compound word - Mobile + Beeline.
Our mobile service makes a straight line between two or more places.

This project is an emotional mobile service based on wearable technology. The basic focus of this project is to stimulate people's emotions with an interaction between mobile and wearable technology, and to develop a social network service between friends.

The main goal is to create a wearable Bluetooth accessory that can receive data from a mobile phone. For example, let us assume that there are two mobile phone users. One user can send operative directions to the other's clothes as the user wants. Without the two users having to meet, they can share their feelings and emotions by sending signals to each other's clothes. Using our service, they will be changed the colors of each others garments, certain patterns or they can send emoticons to LEDs on the garment.

Researchers from the University of Texas Medical Branch and Rice University have succesfully tested the ability of carbon nanotubes to carry electrical signals to nerve cells. From the press release:

The group employed two different types of cells in their experiments, neuroblastoma cells commonly used in test-tube experiments and neurons cultured from experimental rats. Both cell types were placed on ten-layer-thick "mats" of single-walled carbon nanotubes (SWNTs) deposited on transparent plastic. This enabled the researchers to use a microscope to position a tiny electrode next to individual cells and record their responses to electrical pulses transmitted through the SWNTs.

In addition to their electrical stimulation experiments, the scientists also studied how different kinds of SWNTs affected the growth and development of neuroblastoma cells. They compared cells placed on mats made of "functionalized" SWNTs, carbon nanotubes with additional molecules attached to their surfaces that may be used to guide cell growth or customize nanotube electrical properties, to cells cultured on unmodified "native" carbon nanotubes and conventional tissue culture plastic.

"Native carbon nanotubes support neuron attachment and growth well - as we expected, better than the two types of functionalized nanotubes we tested," Pappas said. [Todd Pappas, director of sensory and molecular neuroengineering at UTMB's Center for Biomedical Engineering -ed.] "Next we want to find a way to functionalize the nanotubes to make neuron attachment and communication better and make these surfaces more biocompatible."

According to Unwired View, Motorola has recently put forth a patent for the Feng Shui Phone, which has the following functionalities:

• Three-dimensional Hall-effect sensor for measuring the strength of electromagnetic fields and to form a compass to determine the geographic direction in which the main wall of the house faces.
• Digital camera to determine color saturation, order and balance of the surroundings.
• GPS receiver to determine geographic location of the phone.
• The coordinates are then sent to the GIS databse through wireless network to to get the information about the surroundings of the location, e.g. the distance from the undesirable sites such as major airports, landfills, and factories.
• Cellphone microphone is used to measure noise level of the location.
• AM/FM radio to measure the AM and FM transmission strength and the distance form nearest AM/FM towers.
• The table with the chi values of each parameter is stored in phones memory and is used for calculation of chi  values of different parameters.

Toward direct biocontrol using surface EMG signals: Control of finger and wrist joint models.

Med Eng Phys. 2006 May 6;

Authors: Reddy NP, Gupta V

Increased interest in virtual reality (VR) and telemanipulation has created a growing need for the development of new interfacing devices for measuring controlling actions of the human hand. The objective of the present study was to determine if surface electromyography signals (SEMG) from the flexor digitorum superficialis (FDS), and flexor carpi ulnaris (FCU) generated during flexion-extension of the human index finger and wrist can be used for controlling the flexion-extension of the finger and wrist of a simple geometric computer model. A simple geometric computer model of finger and wrist joints was developed. Eighteen subjects controlled the computer model using the SEMG signals from their FDS and FCU. The results indicate that the SEMG signals from the FDS and FCU muscles can be used as a direct biocontrol technique for controlling the finger and wrist models. This study establishes the proof of concept for direct biological control of the dynamic motion of the finger and wrist models for use in virtual reality environments and telemanipulation.

Neural substrates for motor imagery in severe hemiparesis.

Neurorehabil Neural Repair. 2006 Jun;20(2):268-77

Authors: Kimberley TJ, Khandekar G, Skraba LL, Spencer JA, Van Gorp EA, Walker SR

BACKGROUND: . The beneficial effects of imagined movements on motor learning and performance suggest that motor imagery is functionally close to preparatory and executive motor processes. OBJECTIVE: . The purpose of this study was to examine the cortical processes associated with imagery of movement of the wrist in subjects with severe hemiparesis. METHODS: . During fMRI, subjects with stroke performed alternating blocks of imagining wrist-tracking movements with the hemiparetic hand, active wrist-tracking movements with the unaffected hand, and resting. Control subjects performed the same tasks using an assigned hand. Cortical activation in the primary motor (M1), primary sensory (S1), supplementary motor area (SMA), and pre-SMA regions was determined through a laterality index of active voxels and signal intensity. Ability to imagine was assessed with an Imagery Rating Scale. RESULTS: .All subjects displayed primarily contralateral control during the track condition. Healthy subjects demonstrated contralateral control in all areas during the imagine condition, whereas subjects with stroke displayed primarily contralateral activation in S1 but ipsilateral in M1 and SMA. The percentage change in signal intensity was greater in the ipsilateral hemisphere in subjects with stroke than in the ipsilateral hemisphere in healthy subjects during the imagine condition. Additionally, subjects with self-reported low ability to imagine displayed no difference in activation compared to those with high imagery ability. CONCLUSIONS: . These findings are consistent with other works demonstrating primarily ipsilateral control of the hemiparetic hand in subjects with functional movement and lay the groundwork for further investigation into the ability of mental imagery to affect functionally relevant cortical control in subjects recovering from stroke.

Janssen Pharmaceutical, a manufacturer of prescription medications for the treatment of schizophrenia and bipolar mania, has developed a schizophrenia training program based on virtual reality technology.

In the program, the participant chooses a virtual experience and is led through a range of visual and auditory hallucinations during a ride on a bus, a trip to the doctor's office or a trip to a pharmacy located in the back of grocery store.

In the virtual program simulating a trip to the pharmacy, the participant hears voices popping in and out of their head. Some are soft, some loud -- even yelling -- and many of them are paranoid. People stare at you from every aisle, some seem to be able to read your mind, others are afraid of you. A person in a television monitor screams at you. As you get to the pharmacy counter you can hear the pharmacists whispering and laughing and then they hand you a prescription of what looks like "poison," with a big scull and cross bones on the bottle's label.

IT IS 2050, and Peter Schwartz is deciding what to do with the rest of his life. He has already had two successful careers and he wants another one before he dies, which he expects to happen in around 50 years. By then he'll be about 150, which isn't bad for a baby boomer, but he expects his son, now 60, to live a lot longer than that.

The world that Schwartz lives in is radically different from the one he grew up in. The industrial and information age has passed into history, overtaken by a revolution in bioscience that began around
