Long Term Memory

Information goes one way from the cortex basil gangliaUnconscious – No feedback to neocortex

Dopamine is the major neurotransmitter

Implicit Memory

Medial Temporal RegionHippocampusAmygdalaEntorhinal Cortex

Degenerates in Alzheimer’sParahippocampal Cortex

Visuospatial processing Perirhinal Cortex

Visual object memory

Explicit Memories

Hippocampus is involved in memory for location of things – mental mapsBetter spatial memory larger hippocampusIE: london taxi drivers

Visual Object Memory

Spatial Memory
