Figure 5.

Schematic showing the proposed balance of action from diencephalic nuclei upon two independent components of recognition memory—recollective-based recognition (R) and familiarity-based recognition (K). The gradation from white (R) to black (K) is used to represent the relative involvement of the various diencephalic nuclei with these two information types. With the exception of the mammillary bodies, it seems unlikely that any other region has a purely selective effect on either R or K. Abbreviations: ATN, anterior thalamic nuclei; Intra, intralaminar thalamic nuclei; MB, mammillary bodies; MD, medial dorsal thalamic nucleus; Mid, midline thalamic nuclei.
