The hippocampus is a part of the forebrain, located in the medial temporal lobe. It belongs to the limbic system and plays major roles in short term memory and spatial navigation. Humans and other mammals have two hippocampi, one in each side of the brain.

New molecular interaction governs formation of specific connections between neurons

Researchers at VIB and KU Leuven have uncovered a new molecular interaction that governs the formation of specific functional connections between two types of neurons.

Critical illness and major infection can promote brain changes, accelerate cognitive decline

Researchers at Johns Hopkins report that a novel analysis of more than a thousand patients adds to evidence that hospitalization, critical illness and major infection may diminish brain structures that are most commonly affected by Alzheimer's disease.

New research provides insight into the way human brain connects episodic memories to solve problems

Humans have the ability to creatively combine their memories to solve problems and draw new insights, a process that depends on memories for specific events known as episodic memory.

Obesity contributes to cognitive deficits by activating microglial cells, mice study shows

Obesity leads to cognitive impairment by activating microglial cells, which consume otherwise functional synapses in the hippocampus, according to a study of male mice published in JNeurosci.

Study analyzes what happens in the brain when humans forget something on purpose

Researchers from Ruhr-Universität Bochum and the University Hospital of Gieβen and Marburg, in collaboration with colleagues from Bonn, the Netherlands, and the UK, have analyzed what happens in the brain when humans want to voluntarily forget something.

Certain cells in hippocampus play key role in risk taking behavior and anxiety

Why do some people comfortably walk between skyscrapers on a high-wire or raft the Niagara Falls in a wooden barrel whereas others freeze on the mere thought of climbing off escalators in a shopping mall? In a new study, scientists have found that a certain type of cells in the hippocampus play a key role.

Researchers describe novel mechanism that links epigenetic change to translational control

Understanding how memories form and are retrieved has applications to psychiatric, neurological and neurodegenerative disorders, and may be helpful to attenuate maladaptive memories in psychiatric disorders.

Single dose of cannabidiol showed effective results in rats with symptoms of depression

Commercial antidepressants typically take two to four weeks to have a significant effect on a depressed patient. They are also inneffective in approximately 40% of the cases.

Radiation therapy impairs new memory formation in pediatric brain tumor patients

Young people who received radiation therapy for the most common pediatric brain tumor struggle to create new memories about specific events, according to a study of children and adolescents published in JNeurosci. Their ability to recall events prior to treatment, however, remains intact.

Pediatric brain tumor patients who undergo radiation less likely to recall recently experienced events

Children with certain types of brain tumors who undergo radiation treatment are less likely to recall the specifics of events they experienced after radiation than to remember pre-treatment happenings, according to a Baylor University study comparing them to children with healthy brains.

Psychologist to assess how the brain maintains precise short-term and long-term memories

A person's general intelligence and ability to understand language are reliant on the brain's ability to maintain precise information acquired over a short period of time.

UAB study shows how ion channel differentiates newborn and mature neurons in the brain

The dentate gyrus of the hippocampus is part of the brain that helps form memories. It is also one of just two areas in the adult brain where new neurons are continuously formed.

New ‘closed-loop’ brain stimulation method improves learning, memory, and skill acquisition

HRL Laboratories, LLC, in collaboration with University of New Mexico, have published the first study showing that transcranial alternating current stimulation of the brain during sleep increases human subjects' ability to accurately assess hidden targets in novel visual scenes.

Study yields new insights into why the system needs sleep

Sleep is essential for brain functionality and overall health but understanding how sleep delivers its beneficial effects remains largely unknown. In an article publishing on August 9 in the open access journal PLOS Biology, Shanaz Diessler and Maxime Jan at the University of Lausanne and the SIB Swiss Institute of Bioinformatics (Switzerland), sleep researchers are exploring new and unbiased approaches that can take sleep to a systems level.
