Aggleton & Brown propose that familiarity-based
recognition depends on a perirhinal-medial dorsal thalamic system.
However, connections between these structures are sparse or absent. In
contrast, the perirhinal cortex is connected to midline/intralaminar
nuclei. In a human, a lesion in this thalamic domain, sparing the
medial dorsal nucleus, impaired familiarity-based recognition while
sparing recollective-based recognition. It is thus more likely that
the intralaminar/midline nuclei are involved in recognition.
