TRANSCRIPT

  • 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?

    Psychophysics

    Electroencephalography(EEG)

    fMRI

    Electrocorticography

    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.

    Invasive

  • 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.

  • Electroencephalography(EEG)

  • 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

  • Thank you
