A developmental gradient of COUP-TFI expression regulates the relative size of hippocampus dorsal and ventral subregions.

PLoS Biology
The hippocampus is a key brain region for learning and memory that can be divided into multiple compartments, including the dorsal and ventral hippocampi. Each compartment has unique functions, connectivity, and molecular properties.

Family Income Mediates the Effect of Parental Education on Adolescents’ Hippocampus Activation During an N-Back Memory Task

Brain Sciences, 2020
Introduction: Hippocampus, a medial temporal lobe structure, has significant implications in memory formation and learning. Although hippocampus activity is believed to be affected by socioeconomic status (SES), limited knowledge exists on which SES ...

Phasic locus coeruleus activity enhances trace fear conditioning by increasing dopamine release in the hippocampus

eLife
Locus coeruleus (LC) projections to the hippocampus play a critical role in learning and memory. However, the precise timing of LC-hippocampus communication during learning and which LC-derived neurotransmitters are important for memory formation in the ...

Two Behavioral Tests Allow a Better Correlation Between Cognitive Function and Expression of Synaptic Proteins

Frontiers in Aging Neuroscience, 2018
The molecular substrate of age-associated cognitive decline (AACD) is still elusive. Evidence indicates that AACD is related to synaptic impairment in hippocampus, but different hippocampal regions play different roles, with the dorsal hippocampus (DH ...

Compensatory Regulation of Excitation/Inhibition Balance in the Ventral Hippocampus: Insights from Fragile X Syndrome

Biology
The excitation/inhibition (E/I) balance is a critical feature of neural circuits, which is crucial for maintaining optimal brain function by ensuring network stability and preventing neural hyperexcitability.

Low-Intensity Transcranial Ultrasound Stimulation Inhibits Epileptic Seizures in Motor Cortex by Modulating Hippocampus Neural Activity

IEEE Transactions on Neural Systems and Rehabilitation Engineering
Prior studies indicate that applying low-intensity transcranial ultrasound stimulation (TUS) to the hippocampus can suppress epileptic seizures. Nevertheless, it is unclear how TUS regulates hippocampal neural activity, and whether and how epileptic ...
