• Integrative neuroscience advances emphasize brain-wide connectivity as the substrate for coordinated cognition and behavior, illustrated by cross-regional mappings of septal, cortical, thalamic, and hippocampal networks across primates and rodents [1], [10], [7], [18].

• Memory, learning, and extinction emerge from limbic circuitry interactions (hippocampus, rhinencephalon, mesial temporal structures) integrated with behavioral training; evident in septal-hippocampal lesion studies and extinction paradigms [2], [3], [6], [15], [14].

• Hemispheric interactions shape perception and cognitive processing; deconnection and 'minor hemisphere' concepts reveal bilateral symmetry constraints and interhemispheric transfer in complex perceptual tasks [5], [13].

• Emergence of integrative neuroscience as a program blending neuropsychology, brain science, and cognitive neuroscience to study systemic brain functions, signaling a shift toward cross-disciplinary inquiry [8], [20], [17], [9].

• Detailed anatomical mapping of converging sensory pathways and cortico-subcortical projections reveals how sensory information integrates to drive motor and cognitive outcomes in the primate brain [10], [18], [19], [9].
