Associations of cannabis use, tobacco use and co‐use with brain volume: A systematic review and meta‐analysis

Addiction, EarlyView.
Abstract Background and aims Cannabis is the most widely used illicit drug worldwide and is often co‐used with tobacco, the leading cause of preventable death. Although cannabis and tobacco have distinct neurobiological actions, their associations with brain volumes are unclear.

Human brain matters: Navigating the neuropathology of COVID‐19

Brain Pathology, EarlyView.
Severe COVID‐19 is associated with vascular dysregulation and chronic neuroinflammation, leading to axonal injury and neurodegeneration. In long COVID or PASC, persistent alterations in neuroimaging and biofluid biomarkers reflect ongoing neuronal damage and neuroinflammation, contributing to long‐term neurological symptoms including fatigue, cognitive

Multisynaptic inputs from the medial temporal lobe to V4 in macaques. [PDF]

PLoS ONE, 2012
Retrograde transsynaptic transport of rabies virus was employed to undertake the top-down projections from the medial temporal lobe (MTL) to visual area V4 of the occipitotemporal visual pathway in Japanese monkeys (Macaca fuscata). On day 3 after rabies

Non‐Alzheimer Aβ deposits in the human CNS: Implications with hypoxia and related conditions

Brain Pathology, EarlyView.
An Aβ deposit in a non‐Alzheimer's brain from an individual who experienced hypoxia/energy failure. Abstract We recently reported the deposition of Aβ in the frontal cortex of individuals who died of acute coronavirus disease 2019 (COVID‐19), or who did not have COVID‐19 but had respiratory distress, or infants with severe cardiac malformations.

Excitatory Postrhinal Projections to Principal Cells in the Medial Entorhinal Cortex [PDF]

The Journal of Neuroscience, 2015
The postrhinal cortex (POR) provides substantial input to the entorhinal cortex, mainly targeting superficial layers of the medial entorhinal cortex (MEC). Major inputs to POR originate in the visual and parietal cortex, thus providing neurons in MEC with a subset of cortical information relevant to their spatial firing properties.

Predictive grid cells: Future spatial representations in the hippocampal-entorhinal circuit

Neuroscience Research
Place cells in the hippocampus and grid cells in the entorhinal cortex have long been interpreted as neural representations of an animal’s current location in space. However, an increasing amount of theoretical and experimental evidence suggests that the

What makes a lonely child: environmental, health, and multimodal neuroimaging correlates of prospective loneliness in the ABCD study

Journal of Child Psychology and Psychiatry, EarlyView.
Background Loneliness in childhood is a growing public health concern, yet early multilevel candidate risk and protective factors remain insufficiently mapped. Systematic investigation is essential to guide prevention and intervention during sensitive developmental periods.

Perirhinal cortex and the neural basis of object memory in the rat [PDF]

, 2002
This thesis aimed to investigate the role of the perirhinal cortex in object memory in the rat. The first experiment tested the hypothesis that the perirhinal cortex is critical to memory for relationships between objects by testing postoperative ...

Recurrent circuits within medial entorhinal cortex superficial layers support grid cell firing

Nature Communications, 2018
Medial entorhinal cortex (mEC) neurons encode various navigation parameters such as speed, head direction, as well as grid cells. Here, the authors demonstrate that brief disruption of the local activity in mEC specifically affects grid cell tuning.
