The team found that those young adults who displayed higher measures of behavioural impulsivity also had lower levels of myelin in the putamen.

The brain area that is composed of the caudate nucleus and putamen.

In addition, through its primary metabolite phenylethylidenehyrazine (PEH), phenelzine causes elevated GABA levels in the caudate-putamen and nucleus accumbens thereby exerting its anxiolytic effects.

(Phenelzine Sulfate, NCI Thesaurus)

Clusters of neurons comprising the globus pallidus, putamen, caudate, nucleus accumbens, substantia nigra and subthalamic nucleus.

(Basal Ganglia, NCI Thesaurus)

A very thin, curved lamina comprised of subcortical gray matter that is lateral to the putamen, medial to the insular cortex, and between the external and extreme capsules.

(Claustrum, NCI Thesaurus)

The researchers discovered that overall brain volume and the volumes of five regions in particular — the caudate nucleus, putamen, nucleus accumbens, amygdala and hippocampus — were smaller in people with ADHD than in others, with the biggest difference occurring in the amygdala.

The putamen is a key brain hub in addiction, sending dopamine signals elsewhere in the brain, and helping mediate how impulsively we behave.

Within these studies, MRI scans measured each participant's overall brain volume plus the volume of seven brain regions thought to be linked to ADHD: the pallidum, thalamus, caudate nucleus, putamen, nucleus accumbens, amygdala and hippocampus.

In a study, a team of researchers at Cambridge’s Department of Psychiatry, in collaboration with a group at Aarhus University in Denmark, has shown a strong association between increased behavioural impulsivity in young adults and abnormalities in nerve cells in the putamen, a key brain region involved in addictive disorders.
