Neuropsych : Sensory Organixation

Filter and transduce energy:
-eg light energy into chemical energy
-airwaves into mechanical energy

Most information we talk about in this class come from exteroreceptive receptors (in this class) because come from external stimuli
interoceptive help us understand pain and hunger

1st: photoreceptive cells capture light (rods and cones). synapse with :
2nd: Bipolar cells which synapse with:
3rd: Ganglion cell layer. branch out and become the optic nerve

-amacrine and horizontal cells mostly facilitate process, like bridges between

Each eye processing half of visual field but there is overlap
-50% will cross and become contralateral, other half are ipsilateral, so left visual field processed by right hemisphere
(note: nasal parts cross over, temporal hemi will travel ipsilateral) and vice versa

Striate cortex, primary visual cortex
-calcarine fissue is right there

Secondary association/prestriate cortex

Visual assembling and mapping (possible colour and form)

1. geniculate-striate pathway
2. tectal-pulbinar pathways
(superior colliculi - back of thalamus)

Visual agnosia

Visual ataxia (not knowing where going, coordination between movement and what seeing

Dynamic form (moving shapes (possibly colour as well)

Colour and form

Direction of motion

Dynamic forms of line orientation-with colour (everything gets put together)
