The hippocampal formation is composed of the Cornu ammonis (areas CA1--CA3), the dentate gyrus and the
subicular complex.

Furthermore, the anomalous appearance of the Calcium binding protein Calbindin (usually present in dendritic inhibitory interneurons, see [1]) has been observed in
subicular axo-axonic cell terminals [15, 31].

subicular interaction with the hypothalamic paraventricular nucleus: Evidence for a relay in the bed nucleus of the stria terminalis.
Hippocampal function (often via
subicular output) is related to a large range of processes: behavioural inhibition, increased negative affective bias, exploration, risk assessment and various aspects of learning and memory (29).
Por su parte, el NACC recibe conexiones del hipocampo procedentes de las regiones CA1, CA2, CA3 y CA4 y del complejo
subicular. La concha tambien recibe proyecciones procedentes del hipotalamo.
Esto podria explicar los aparentes resultados contradictorios obtenidos con lesiones hipocampales, segun el dano hubiera afectado o no selectivamente a la conexion
subicular. Una posterior ampliacion de esta hipotesis implico especificamente al subterritorio "shell", o externo, del nucleo accumbens en la expresion de inhibicion latente, y al subterritorio "core", o central, en el efecto interruptor de esta respuesta.
