Extract

To the Editor: The thalamus is a midline, paired, brain structure broadly composed of anterior, medial, and lateral nuclei.1 Appreciation of thalamic connections is important for the clinician presented with thalamic injury. We explore manifestations of thalamic stroke in a man admitted to a neuropsychiatric unit for aggression. Functional anatomy as it pertains to cognition, arousal, and behavior is explored and management is discussed.
