Cognitive NeuroscienceBy:- Manpreet SinghIIT Roorkee
What is Cognition?All mental abilities and processes related to knowledge, attention, memory, reasoning, computing etc.
HistoryThe term was coined first by George A Miller and Michael Gazzaniga toward the end of the 1970s
History : 19th CenturyLocalization View
Aggregated Field view
Neuropsychology Borcas area
Mapping the brain-Hitzig and Fritsch
History : 20th CenturyNeuron Doctrine
New brain mapping
Birth of Cognitive Neuroscience : combining neuroscience and cognitive science
Why study Cognition?can provide insight into areas of cognitioncan help distinguish between different theories relating to how that process is performed.can help guide the design of artificial intelligence systems intended to mimic human abilities
How Cognition is studied?
Transcranial magnetic stimulation
Psychophysicsthe scientific study of the relation between stimulus and sensation
experiments seek to determine whether the subject can detect a stimulus, identify it, differentiate between it and another stimulus, or describe the magnitude or nature of this difference
ElectrocorticogaphyIt is the practice of usingelectrodesplaced directly on the exposed surface of thebrainto record electrical activity from thecerebral cortex.
Trans-cranial magnetic stimulationTrans-cranial magnetic stimulation(TMS) is a noninvasive method used to stimulate small regions of the brain.
Electroencephalography(EEG)Electroencephalography(EEG) is the recording ofelectricalactivity along thescalp.
fMRIFunctional magnetic resonance imagingorfunctional MRI(fMRI) is afunctional neuro-imaingprocedure usingMRItechnology that measures brain activity by detecting associated changes in blood flow.
As long as our brain is a mystery, the universe, the reflection of the structure of the brain will also be a mystery
