Visual thalamus, “it’s complicated”

Colour through the thalamus.

Visual perception in humans and other primates depends on the retino-thalamo-cortical pathway. This pathway begins with retinal ganglion cells, which have axonal terminations in the lateral geniculate nucleus (LGN) of the thalamus. Each ganglion cell axon provides input to one or more LGN relay neurones and, in turn, nearly all the LGN relay neurones project to the primary visual cortex. Thus, ...

The cognitive thalamus

The thalamus, once viewed as passively relaying sensory information to the cerebral cortex, is becoming increasingly acknowledged as actively regulating the information transmitted to corti-cal areas. There are a number of reasons for this change. First, evidence suggests that first-order thalamic areas, like the lateral geniculate nucleus, ventral division of the medial geniculate nucleus, and...

cortical epandimoma with extention to thalamus

ependymomas are glial tumors originate from ependymal cells lining the ventricles and the central canal of the spinal cord. two thirds of ependymomas arise in the infratentorial or intraventriclesandone-third aredetected in supratentorial area. however supratentorial “cortical” ependymomas are veryuncommon. ependymomas are usually infratentorial, intraventricular tumor, including 2–9% of all ce...

Synchronized Oscillation in the Thalamus

Acad. Sci. U.S.A. 84, 6558 (1987); C. A. Whitlock and 0. N. Witte, ibid. 79, 3608 (1982). 25. A series of 24 18-nucleotide primers with complete identity to the murine Btk cDNA sequence (GenBank L08967) were used to generate 380base pair overlapping products spanning the entire btk coding sequence. Full sequence information is available from the authors. 26. Filter lifts containing 5 x 105 plaq...
