Abnormal functional specialization within medial prefrontal cortex in high-functioning autism: a multi-voxel similarity analysis [PDF]

, 2009
Multi-voxel pattern analyses have proved successful in decoding mental states from fMRI data, but have not been used to examine brain differences associated with atypical populations. We investigated a group of 16 (14 males) high-functioning participants

Allocentric directional processing in the rodent and human retrosplenial cortex [PDF]

, 2014
Head direction cells in the rodent brain have been investigated for a number of years, providing us with a detailed understanding of how the rodent brain codes for allocentric direction.

Spatiotemporally random and diverse grid cell spike patterns contribute to the transformation of grid cell to place cell in a neural network model.

PLoS ONE, 2019
The medial entorhinal cortex and the hippocampus are brain regions specialized in spatial information processing. While an animal navigates around an environment, grid cells in the medial entorhinal cortex spike at multiple discrete locations, forming ...

Diffusion imaging markers of accelerated aging of the lower cingulum in subjective cognitive decline

Frontiers in Neurology
IntroductionAlzheimer’s Disease (AD) typically starts in the medial temporal lobe, then develops into a neurodegenerative cascade which spreads to other brain regions.

GluK2-mediated excitability within the superficial layers of the entorhinal cortex.

PLoS ONE, 2009
Recent analysis of genetically modified mice deficient in different kainate receptor (KAR) subunits have strongly pointed to a role of the GluK2 subunit, mediating the vulnerability of the brain towards seizures.

A sense of place: a model of synaptic plasticity in the hippocampus

, 2013
Artificial synaptic plasticity is a programming approach used in artificial neural simulations to replicate the change in efficacy between two synapses observed in biological neurons.

Heterosynaptic NMDA receptor plasticity in hippocampal dentate granule cells

Frontiers in Synaptic Neuroscience
The dentate gyrus is a key relay station that controls information transfer from the entorhinal cortex to the hippocampus proper. This process relies heavily on dendritic integration by dentate granule cells (GCs) of excitatory synaptic inputs from the ...

Hippocampal CA1 replay becomes less prominent but more rigid without inputs from medial entorhinal cortex

Nature Communications, 2019
Medial entorhinal cortex (MEC) is involved in memory processes that entail the replay of sequential firing of hippocampal place cells during rest periods and during behaviour.

Separating the Functions of the Medial and Lateral Entorhinal Cortex: Differential Involvement in Spatial and Non-spatial Memory Retrieval [PDF]

, 2011
Anatomical connectivity and single neuron coding suggest a dissociation of information representation within the lateral and medial entorhinal cortex, a brain region with widespread connections to cortical areas. We aimed to expand this idea by examining
