Thalamus
The Diencephelon is composed of four parts.
Thalamus, Subthalamus, Epithalamus and Hypothalamus.
Divides the thalamus in Y shape formation.
What is the internal medullary lamina?
This level deals with thalamic-cortical networks are involved in sensory and motor learning.
What is the Dorsal Level of the Thalamus?
Has afferent connections to the organ of Corti of both ears.
What is the Medial Geniculate Body?
Deals with Vision
Lateral Geniculate Body
Mediates endocrine and other Deals with body temperature, water balance, and sugar and fat metabolism.
What is the autonomic nervous system?
Deals iwth emotion, judgement, reasoning, memory, language and cognitive functions.
Hint: Its part of the Medial Nuclear Complex
Dorsomedial Nucleus
Important for regulation of volitional movements, with afferent connections to the contralateral cerebellar hemisphere.
Has connections to the Basal Ganglia.
What is the Ventrolateral Nucleus?
Finds its connections with the hippocampus, cingulate gyris, and hypothalamus.
Deals with digestion, breathing, urogenital, emotional endocrine.
Anterior Nucleus
Loss of vision in contralateral halves of visual fields, also called homonymous hemianopsia.
What is the Lateral Geniculate Body?
Who does pain, taste, temperature, audition and vision
A poorly understood nucleus. Contributes to visceral-sensory integration for behavioral responses.
What is Lateral Dorsal Nucleus?
Relay to somatosensation (pain, temperature, and discriminative touch) from body to face.
What is Ventral Posterior Nucleus
Has afferent connections from the globus pallidus, vestibular nuclei, superior colliculus, and brainstem reticular formation.
Has efferent projections to project basal ganglia and partly goes to Cerebral Cortex
What is Intralaminar Nuclei?
The Lesions to this Thalamic Nucleus deals with rage, anxiety-related disorders and memory loss aka Wernicke-Korsakoff syndrome.
What is the Dorsomedial Nucleus?
Deals with higher mental functions. Deals with language formulation, lexical storage, and processing, reading, and writing.
What is Pulvinar?
Yet another not well understood nucleus. Deals with sensory integrative areas of the parietal lobe. Such as vision, tactile, and audition prior to responses.
What is Lateral Posterior Nucleus?
Sensations of taste, pain, temperature, and discriminative touch head and face. Also... If its sensations of the head and face. What connection can we deduce it to?
Ventral Posterior Medial Nucelus/CN V
Electrical stimulation and ablation of the nucleus induces changes in blood pressure, anxiety levels, and emotional.
What is the Anterior Nucleus?
