from the,Olfaction is the only sensory system that is Specific nuclei in the thalamus are connected to other limbic system structures including the mammillary bodies and hippocampus.In fact, attention and focus disorders such as obsessive-compulsive disorder are specifically attributed to damage or physiological malfunctions of this circuit due to its role in regulating task-dependent activities during a state of rest.
adj., adj thalam´ic. ; The thalamus is connected to the hippocampus via the mammillothalamic tract. The thalamus is a small structure within the brain located just above the brain stem between the cerebral cortex and the midbrain and has extensive nerve connections to both. See more.

to the interthalamic adhesion.The thalamus has numerous connections to many, many parts of the brain and so has several different functions. An example is the separation or divorce of their parents. Enter any psychology term. Thalamus, plural thalami, either of a pair of large ovoid organs that form most of the lateral walls of the third ventricle of the brain.The thalamus translates neural impulses from various receptors to the cerebral cortex. The thalamus (from Greek θάλαμος, "chamber") is a large mass of gray matter located in the dorsal part of the diencephalon (a division of the forebrain).
past these few – with the exception of olfactory sensations. They are defined by their locations, functions, and anatomy.
Nerve fibers project out of the thalamus to the cerebral cortex in all directions, allowing hub-like exchanges of information.

Additionally, it is central to the process of impulse inhibition. SHH signaling from the MDO induces a posterior-to-anterior wave of expression the proneural gene,This zonation of proneural gene expression leads to the differentiation of glutamatergic relay neurons from the Neurogenin1+ precursors and of GABAergic inhibitory neurons from the Ascl1+ precursors.
