Basal Ganglia, Thalamus, and Hypothalamus
Captions available
The idea
The basal ganglia regulate movement and motivation, the thalamus relays sensory and motor signals to the cortex, and the hypothalamus regulates hormone release and body-temperature homeostasis.
In practice
Damage to the basal ganglia in Parkinson's disease produces a characteristic shuffling gait alongside motor impairment.
Where people slip
The thalamus routes nearly all sensory information except olfaction — smell reaches the cortex by a separate route.
