An Operant-based Touchscreen Morph Discrimination Task Does Not Detect Age-related Mnemonic Similarity Deficits in Rats

This study develops a touchscreen-based morph discrimination task for rats and finds no age-related mnemonic similarity deficits, contrasting previous 3D object-based findings.

A long-term ketogenic diet in young and aged rats has dissociable effects on prelimbic cortex and CA3 ensemble activity

This study examines the effects of a ketogenic diet on neural activity in the prelimbic cortex and CA3 of young and aged rats, finding increased activation in the PL but no change in CA3.

Unilateral Perforant Path Transection Does Not Alter Lateral Entorhinal Cortical or Hippocampal CA3 Arc Expression

This study examines if perforant path fiber loss affects Arc expression in CA3 and LEC, finding no change in Arc expression despite impaired task performance.

Age-related alterations in prelimbic cortical neuron Arc expression vary by behavioral state and cortical layer

The paper examines age-related changes in Arc expression in prelimbic cortical neurons during behavior, finding reduced expression linked to multitasking deficits, with no projection neuron specificity in the prelimbic cortex unlike the perirhinal cortex.

Multi-scale Imaging Reveals Aberrant Connectome Organization and Elevated Dorsal Striatal Arc Expression in Advanced Age

This study uses multi-scale imaging to show that aged rats have altered functional connectivity and increased dorsal striatal Arc expression during cognitive multi-tasking.

Experience-dependent effects of muscimol-induced hippocampal excitation on mnemonic discrimination

This study investigates how muscimol-induced hippocampal excitation affects mnemonic discrimination in rats, finding that it impairs performance on novel stimuli but not familiar ones.
