Anatomy of anterior thalamic nucleus Blood supply Tuberothalamic (Polar) artery form P-com Afferent *Mammillary body (mammillothalamic tract) *Ventral amygdalofugal fiber (inferior thalamic peduncle) Efferent cingulate gyrus
Input Nucleus Output Amygdala/perirhinal cortex Inferior temporal cortex Hypothalamus Intralaminar thalamic nucleus dorsomedial thalamus pre-frontal lobes mamillary bodies... anterior nuclei cingulate gyrus & hippocampus Supplementary motor Anterior insular cortex
Ventral amygdalofugal fiber through anterior perforated substance to basal nuc Meynert, HT, MD thalamus
Neuropsychological disturbances of Ant. Thalamic lesion Disturbances of alertness Intralaminar, reticular, ventral anterior nuclei Apathy , disinterest, lack of drive for motor expression anterior thalamic nucleus- cingulate gyrus: frontal hypometabolism Memory disturbance * Mammillothalamic tract * Ventral amygdalofugal fiber (perirhinal cortex) Left : verbal, Right: visuospatial Anterograde, sometimes retrograde, disorientation to time, normal working memory
Aphasia of thalamic lesions Anterior thalamic lesion Aspontaneity, diminished content of speech, paraphasia, decreased generation of words, defects of spelling, comprehension, reading and writing, preserved repetition Paramedian thalamic lesion Poor initiation of speech, poverty of output, occasional confabulation, lack of output monitoring, intact repetition, deficit in word-list generation and naming, perceptive errors, nonaphasic misnaming, intrusion, perseveration Non phonemic or semantic paraphsia “ Subtranscortical aphasia” Lack of initiation of speech, disruption of speech by memory and arousal disturbances Damage to the frontal lobe- inferior thalamic peduncle-nucleus reticularis-centre median system In our cases = anomic aphasia :Frontal dysfunction?, lexicon damage
