Parallel and convergent processing in grid cell, head-direction cell, boundary cell, and place cell networks. [PDF]

open access: yes, 2013
The brain is able to construct internal representations that correspond to external spatial coordinates. Such brain maps of the external spatial topography may support a number of cognitive functions, including navigation and memory.

Hippocampal TERT Regulates Spatial Memory Formation through Modulation of Neural Development

open access: yesStem Cell Reports, 2017
Summary: The molecular mechanism of memory formation remains a mystery. Here, we show that TERT, the catalytic subunit of telomerase, gene knockout (Tert−/−) causes extremely poor ability in spatial memory formation.

Postmortem Studies of the Hippocampal Formation in Schizophrenia [PDF]

open access: yesSchizophrenia Bulletin, 1997
Many postmortem studies report differences between the hippocampal formations of patients with schizophrenia and those of controls. These differences include volume changes, cell density changes, periventricular gliosis, senile degenerative changes, and abnormalities of neuronal size, position, or orientation.

Distribution of Phosphorylated TrkB Receptor in the Mouse Hippocampal Formation Depends on Sex and Estrous Cycle Stage

open access: yesJournal of Neuroscience, 2011
Tropomyosin-related kinase B receptor (TrkB) is a neurotrophin receptor important for the synaptic plasticity underlying hippocampal-dependent learning and memory.

Hippocampal structural plasticity accompanies the resulting contextual fear memory following stress and fear conditioning [PDF]

open access: yes, 2013
The present research investigated the resulting contextual fear memory and structural plasticity changes in the dorsal hippocampus (DH) following stress and fear conditioning. This combination enhanced fear retention and increased the number of total and

Integrating Spatial Working Memory and Remote Memory: Interactions between the Medial Prefrontal Cortex and Hippocampus [PDF]

open access: yes, 2017
In recent years, two separate research streams have focused on information sharing between the medial prefrontal cortex (mPFC) and hippocampus (HC).

Properties of Contextual Memory Formed in the Absence of αCaMKII Autophosphorylation

open access: yesMolecular Brain, 2011
The alpha-isoform of calcium/calmodulin-dependent kinase II (αCaMKII) is a major synaptic kinase that undergoes autophosphorylation after NMDA receptor activation, switching the kinase into a calcium-independent activity state.

Unraveling the Hippocampal Molecular and Cellular Alterations behind Tramadol and Tapentadol Neurobehavioral Toxicity

open access: yesPharmaceuticals
Tramadol and tapentadol are chemically related opioids prescribed for the analgesia of moderate to severe pain. Although safer than classical opioids, they are associated with neurotoxicity and behavioral dysfunction, which arise as a concern ...

Reduced Cyclic Adenosine Monophosphate Level in Hippocampal CA1 Participates in Propofol Induced Amnesia in Rats

open access: yesFrontiers in Neuroscience, 2018
Propofol inhibits long-term potentiation (LTP) in the hippocampal CA1 region and impedes episodic memory formation. However, the molecular mechanisms involved in the effect of propofol are still poorly understood.
