Introduction and Anatomical Context of the Putamen The Putamen is a crucial subcortical structure within the forebrain, serving as a principal component of the basal ganglia. This deep-brain nuclear complex is centrally important for coordinating movement, establishing habits, and integrating motor and reward signals. Anatomically, the putamen forms the lateral wall of the striatum, merging […]
Dyssocial Reaction: Neurobiological Considerations A growing body of evidence is beginning to suggest that various forms of behavior that are commonly referred to as ‘antisocial’ or ‘dysfunctional’ may in fact be the result of neurobiological factors. This paper will discuss the neurological and neurobiological underpinnings of dyssocial reaction, an umbrella term encompassing a range of […]
Introduction and Anatomical Definition The Lateral Hypothalamus (LH) constitutes a fundamental and highly heterogeneous region situated within the basal forebrain, forming a critical component of the larger hypothalamic structure. This anatomical placement endows the LH with unparalleled access to critical input and output pathways, allowing it to serve as a central regulatory hub for numerous […]
The Mesostriatal System: Neural Basis of Movement and Reward The Core Definition of the Mesostriatal System The mesostriatal system is a critical set of neural pathways within the central nervous system, primarily defined by its dense connections originating in the brainstem and projecting into the Basal Ganglia, a deep group of subcortical nuclei. At its […]
