  2. Trigeminal lemniscus - Wikipedia

    en.wikipedia.org/wiki/Trigeminal_lemniscus

    The trigeminal lemniscus or the trigeminothalamic tracts is a somatosensory tract containing second-order neuron fibers of the trigeminal system.It consists of the ventral and dorsal trigeminal tracts.

  3. Ventral trigeminal tract - Wikipedia

    en.wikipedia.org/wiki/Ventral_trigeminal_tract

    The first-order neurons from the trigeminal ganglion enter the pons and synapse in the principal (chief sensory) nucleus or spinal trigeminal nucleus.Axons of the second-order neurons cross the midline and terminate in the ventral posteromedial nucleus of the contralateral thalamus (as opposed to the ventral posterolateral nucleus, as in the dorsal column medial lemniscus (DCML) system).

  4. Ventrobasal complex - Wikipedia

    en.wikipedia.org/wiki/Ventrobasal_complex

    The ventrobasal complex (VB) is a relay nucleus of the thalamus for nociceptive stimuli received from nociceptive nerves. The VB consists of the ventral posteromedial nucleus (VPM) and the ventral posterolateral nucleus (VPL). In some species, the ventral posterolateral nucleus, pars caudalis is also a part of the VB.

  5. Thalamus - Wikipedia

    en.wikipedia.org/wiki/Thalamus

    The thalamus has many connections to the hippocampus via the mammillothalamic tract. This tract comprises the mammillary bodies and fornix. [27] The thalamus is connected to the cerebral cortex via the thalamocortical radiations. [28] The spinothalamic tract is a sensory pathway originating in the spinal

  6. Human brain - Wikipedia

    en.wikipedia.org/wiki/Human_brain

    Beneath the lateral ventricles is the thalamus and to the front and below is the hypothalamus. The hypothalamus leads on to the pituitary gland. At the back of the thalamus is the brainstem. [27] The basal ganglia, also called basal nuclei, are a set of structures deep within the hemispheres involved in behaviour and movement regulation. [28]

  7. Thalamic fasciculus - Wikipedia

    en.wikipedia.org/wiki/Thalamic_fasciculus

    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.

  8. Sensory gating - Wikipedia

    en.wikipedia.org/wiki/Sensory_gating

    Information from sensory receptors make their way to the brain through neurons and synapse at the thalamus. The pulvinar nuclei of the thalamus plays a major role in attention, and has a major role in filtering out unnecessary information in regards to sensory gating. In a proven clinical study, it has been found out that the two stimuli (S1 ...

  9. Diencephalon - Wikipedia

    en.wikipedia.org/wiki/Diencephalon

    The diencephalon encloses a cavity called the third ventricle. The thalamus serves as a relay centre for sensory and motor impulses between the spinal cord and medulla oblongata, and the cerebrum. It recognizes sensory impulses of heat, cold, pain, pressure etc. The floor of the third ventricle is called the hypothalamus.
