From an anatomical perspective, the concept that the anterior and posterior hippocampus fulfill distinct cognitive roles may seem unsurprising. When compared with the posterior hippocampus, the anterior region is proportionally larger, with visible expansion of the CA1 subfield and intimate continuity with adjacent medial temporal lobe (MTL) structures such as the uncus and amygdala. However, […]

People form memories of specific events and use those memories to make predictions about similar new experiences. Living in a dynamic environment presents a challenge: How does one represent valid prior events in memory while encoding new experiences when things change? There is evidence for two seemingly contradictory classes of mechanism: One differentiates outdated event […]

Ambient noise disrupts vocal communication amongst animals. Recent studies show that some species, such as marmosets, can rapidly adjust the patterns of ongoing calls according to noisy environments. This substantial vocal flexibility reveals that non-human primates have more advanced cognitive control over when and what to vocalize than previously thought. Read Full Article (External Site) […]
