The interthalamic adhesion (also known as the massa intermedia, intermediate mass or middle commissure) is a flattened band of tissue that connects both parts of the thalamus at their medial surfaces. The medial surfaces form the upper part of the lateral wall to the third ventricle.
The rostral thalamus will give rise to the reticular nucleus mainly whereby the caudal thalamus will form the relay thalamus and will be further subdivided in the thalamic nuclei. [ 54 ] In humans, a common genetic variation in the promoter region of the serotonin transporter (the SERT-long and -short allele: 5-HTTLPR ) has been shown to affect ...
The thalamic fasciculus is a component of the subthalamus (ventral thalamus). It is synonymous with field H 1 of Forel.Fibers from the lenticular fasciculus (field H 2 of Forel), are joined by fibers from the ansa lenticularis – different parts of the internal globus pallidus, before they enter the ventral anterior nucleus of the thalamus to form the thalamic fasciculus.
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 ...
They connect with the fibers of the lenticular fasciculus in the field H of Forel to form the thalamic fasciculus. The lenticular fasciculus is composed of fibers that pass from the internal part of the globus pallidus , through the posterior limb of the internal capsule , around the zona incerta .
The spinothalamic tract is a nerve tract in the anterolateral system in the spinal cord. [1] This tract is an ascending sensory pathway to the thalamus.From the ventral posterolateral nucleus in the thalamus, sensory information is relayed upward to the somatosensory cortex of the postcentral gyrus.
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 ...
Lamina affixa is a layer of epithelium growing on the surface of the thalamus and forming the floor of the central part of lateral ventricle, on whose medial margin is attached the choroid plexus of the lateral ventricle; it covers the superior thalamostriate vein and the superior choroid vein.
