Brain Fingerprinting!!!!!!!!! Detection spot!!!!!!!!!

 What is brain fingerprinting?

Brain electrical oscillation signature profiling is a method of interoogation where the suspect's participation in the crime is investigated by studying the brain's response.

A neuro-psychological method of interrogation in which the suspects participation in the crime is investigated by studying the brain's response.



*** It uses the Electroencephalography (EEG) to study the electrical behaviour of the human brain. The suspect is made to sit in a comfortable chair in a soundproof room with a cap having dozens of electrodes attached to it. The other ends of the electrodes are connected to an electroencephalographic (EEG) machine.

To check the activity and triggering of neuron's in the suspect's brain which then generate brainwaves due to documents shown to the suspect which are related to the case.


What is P300?

The P300 is a compnent of the event-related brain potential (ERP) . It means that the response is electrically positive (P) and has a latency of at least 300 ms (300)

What is P300-MERMER?

P300-MERMER is a memory and encoding related multifaceted electroencephalographic response. It comes along with the head gear. P300 is based on oddball paradigm.

MERMER- Memory and Encoding Related Multifaceted  Electroencephalographic response.

Detection of brain waves due to guilt:

Different coloured lines: Red - (Theta) - Information is expected to know; Green - (Alpha) - Information not to suspect; Blue- (Beta) Information of the crime that only perpetrator would know.

The test is based on two phenomenons: Knowledge and Experience

Knowledge: The suspect's brain might have knowledge about the crime committed and the alibi they have come up with.

Experience: The suspect's experience of having participated in the crime determines the guilt.

* When brain fingerprinting was first used?

Dr.Farwell conducted a Brain Fingerprinting test on murder suspect- A woodcutter named James Grinder confessed murdering a woman named Julie Helton. The test proved that the record stored in Grinder's brain matched the scene of the murder of the Julie Helton.

It is a computer based technology designed to determine hidden information in individual's brain by measuring electrical brain wave responses to words, phrases, or pictures presented on a computer screen.

Advanced plant Habitat: A derivation of NASA info : Overview

Image
  Advanced Plant Habitat !!!!!!!! The Advanced plant habitat is a fully automated facility that will be used to conduct plant bioscience research on the International Space station. The system was developed by NASA and ORBITEC. The systems components are managed by and processed for flight at the agency's Kennedy Space Center in Florida. Located in the Kibo module on the ISS, the APH was designed for a 10-year mission for colleting physiological data of plant responses to the spaceflight environment. This data will improve our understanding of how terrestrial biology responds to reduced gravity which is useful for enabling the manned exploration of space. Advanced Plant habitat components: Structural mounting assembly  Air Filtration Assembly  Plant habitat facility kits  Science carrier Growth chamber  Environmental control system Fluid International Subrack Interface Standard Drawer Orbital component unit component drawer Growth light assembly  It's a ful...
