basics of neural systems Flashcards
2 photon imaging
image groups of cells
microelectrodes
detect voltage changes outside of the cell
V1 is also known as ____ cortex
striate cortex
Lashley: The engram
only LARGE lesions = memory loss (tested a range of little lesions all over)
Memories for complex tasks: stored DIFFUSELY throughout cortex
Supports distributed theory
Penfield 3 discoveries
Discovery of somatotopic cortex (somatosensory homunculus)
Temporal lobe: memories
Occipital: visual cortex
motion agosia
what & location
Problems perceiving motion from vision
Damage: MT/V5
Cerebral Achromatopsia:
Colour blindness b/c cortical damage (b&w)
Strokes to v4 in monkeys
Lingual and posterior fusiform gyri in humans
visual object agnosia
Had no meaning to objects
Damage: fusiform, lingual & adjacent part of posterior cingulate gyri
prosopagnosia
Visual agnosia of faces
Area IT: faces and fine objects
