The Brain

Human brain contains about 100 billion of massively (connected?) neurons (nerve cells). It has the incredible capacity to capture an image/scene, perceive, judge, calculate, reason, learn (what not) through the formation of neural networks with the exchange of electrochemical impulses among the neurons (probably nature inspired optimum ways) to achieve a task. Unfolding and understanding ways the neurons interact in temporal and spatial domains even including the third dimension is the motto of the experiments being conducted under controlled environment followed by uncontrolled or day to day normal environment.

Faculty, and researchers may contact us for the collaborative efforts to be made in these directions.

Computer Interface

Brain Computer Interface (BCI) is an intelligent system that creates a direct communication path between the human neuronal system and external devices by directing human intentions into control signals. Therefore, BCI systems provide an interface for communication and control capability of an external device to individuals who suffer from neuromuscular disorders caused by amyotrophic lateral sclerosis, spinal cord injury or brain stroke. The key properties of a BCI are: A BCI must be able to record or capture the brain activity directly. It must be capable of providing feedback to the user in real-time. Finally, the system must be able to provide intentional control which enables the user to perform a particular task based on his/her intentions.


Signal processing is another challenging area when it comes to dealing with the brain signals. The process requires the insight of the probable changes in the human brain in the form of variation in blood circulation, neuronal impulse generation, way of interactions among different regions so that appropriate method for measurement of activation state of the human brain can be chosen. We have limited our efforts on the use of non-invasive ways of capturing brain signals which may not be very accurate. And these types of (non-invasive) signals are the cumulative responses of the nerve cells of the human brain human brain and as such may not be accurately revealing about the dynamics of neuron cells.

More revealing works can be carried out in collaboration with other having requisite infrastructural facilities and experts like neuro surgeons for capturing more accurate neuronal signals.
