A thalamus damaged by a stroke can lead to thalamic pain syndrome, [67] which involves a one-sided burning or aching sensation often accompanied by mood swings. Bilateral ischemia of the area supplied by the paramedian artery can cause serious problems including akinetic mutism, and be accompanied by oculomotor problems.
The thalamic reticular nucleus is part of the ventral thalamus that forms a capsule around the thalamus laterally. However, recent evidence from mice and fish question this statement and define it as a dorsal thalamic structure. [1] [2] It is separated from the thalamus by the external medullary lamina.
In the human brain, the central lateral nucleus is a part of the anterior intralaminar nucleus in the thalamus. [1]: 2 The intralaminar nuclei project to many different regions of the brain, [2] The thalamus acts generally as a relay point for the brain for other areas of the brain to link to. The central lateral nucleus acts in a vital role in ...
In neuroanatomy, the lateral geniculate nucleus (LGN; also called the lateral geniculate body or lateral geniculate complex) is a structure in the thalamus and a key component of the mammalian visual pathway. It is a small, ovoid, ventral projection of the thalamus where the thalamus connects with the optic nerve. There are two LGNs, one on the ...

Ascending reticulothalamic fibres project from the medial zone nuclei of the reticular formation to the hypothalamus (to mediate autonomic nervous system response), and the intralaminar thalamic nuclei (to mediate a startle response to pain).
The ventral posterolateral nucleus (VPL) is one of the subdivisions of the ventral posterior nucleus in the ventral nuclear group of the thalamus. [1] It relays sensory information from the second-order neurons of the neospinothalamic tract and medial lemniscus (of the dorsal column-medial lemniscus pathway) which synapse with the third-order neurons in the nucleus.
Thalamencephalon (Latin: thalamencephalon), also called thalamic region (regio thalamica) or thalamic complex (complex thalamica) is a complex structure comprising thalamus (in the wider sense of the term thalamus, i.e. dorsal thalamus, or thalamus proper, plus subthalamus, or ventral thalamus) and several adjacent structures: epithalamus and metathalamus.
