The amygdala connects to the thalamus both through the amygdalofugal pathway and through a direct connection to the dorsomedial nucleus of the thalamus. [13] After leaving the substantia innominata , the ventral amygdalofugal pathway continues on a medial path to enter the septal region, the lateral preoptic area , the hypothalamus , and the ...
Cortico-cortical coherence is commonly studied using bipolar channels of EEG recordings, as well as unipolar channels of EEG or MEG signals; however, unipolar channels are usually used to estimate the brain sources and their connectivity, using electrical source imaging and connectivity analysis.
Corticomuscular coherence was initially reported between MEG and EMG [1] and is widely studied between EMG and EEG, MEG, etc. . The origins of corticomuscular coherence seem to be communication in corticospinal pathways between primary motor cortex and muscles.
The loop involves connections between the cortex, the basal ganglia, the thalamus, and back to the cortex. It is of particular relevance to hyperkinetic and hypokinetic movement disorders , such as Parkinson's disease and Huntington's disease , [ 1 ] as well as to mental disorders of control, such as attention deficit hyperactivity disorder ...
The claustrum (Latin, meaning "to close" or "to shut") is a thin sheet of neurons and supporting glial cells in the brain, that connects to the cerebral cortex and subcortical regions including the amygdala, hippocampus and thalamus.
The capsule itself appears as a thin white sheet of white matter. [1] The external capsule is a route for cholinergic fibers from the basal forebrain to the cerebral cortex. The putamen separates the external capsule from the internal capsule medially and the claustrum separates it from the extreme capsule laterally.
Papez's paper on the emotional circuit which involved the connection between the hypothalamus and the limbic lobe set MacLean on a journey to learn more. He visited Papez at Cornell University after which he proposed a modified version of the Papez circuit in 1952, emphasizing not only the hippocampus, but also the amygdala and septum. [20]
