How we change what others think, feel, believe and do
The caudate nucleus (also called the caudatum) is a key part of the learning and memory systems, particularly in feedback processing.
It is believed that the caudate nucleus has a regulating role in controlling the threshold potential for general neuron activation and thereby preventing overload through positive feedback loops.
Recent research shows the caudate nucleus may also be involved in feelings of love.
The globus pallidus (Latin for 'pale globe') has some part in filtering external stimuli and may thus prevent overload.
The putamen is largely connected to the substantia nigra and the globus pallidus. It regulates movement and influences learning.
The putamen is connected with degenerative neurological disorders such as Parkinson’s disease.
It has inputs from the prefrontal cortex, amygdala, and dopaminergic neurons in the tegmentum. It sends axons to the globus pallidus, which forwards the signal to the thalamus and hence the pre-frontal cortex.
The nucleus accumbens is a significant element in the mesolimbic dopamine pathway and is thought to be significant in reward, laughter, pleasure, addiction, fear, and the placebo effect.
