Towards deep learning with segregated dendrites

eLife, 2017
Deep learning has led to significant advances in artificial intelligence, in part, by adopting strategies motivated by neurophysiology. However, it is unclear whether deep learning could occur in the real brain.

Reduced CB1 Cannabinoid Receptor Expression in Alzheimer's Disease and Transgenic Mouse Models

AGING MEDICINE, EarlyView.
CB1 receptor (CB1R) expression was significantly reduced in the hippocampus, medial frontal gyrus, and superior temporal gyrus of Alzheimer's patients. CB1R levels negatively correlated with amyloid‐β and tau pathology. In addition, CB1R expression was also reduced in the cortex of 5xFAD mice and in the hippocampus of Tg4‐42 mice.

Functional Segregation of Epileptogenicity within the Human Amygdala

Annals of Neurology, EarlyView.
Objective In temporal lobe epilepsy (TLE), the amygdala in the epileptogenic network is underestimated compared to other regions such as the hippocampus. Recent advances in anatomical neuroimaging and stereoelectroencephalography (SEEG) signal analyses could help better understand the involvement of the different amygdala nuclei in the genesis of ...

Neuron impairment or loss in brain may be responsible for type 2 diabetes and essential hypertension [PDF]

, 2010
Type 2 diabetes and essential hypertension are both very common chronic diseases. Type 2 diabetes is often associated with hypertension, but the exact causes of them are unknown.

Association between Plasma P‐tau217 and Alzheimer's Copathology and Cognitive Decline in Parkinson's Disease

Annals of Neurology, EarlyView.
Objective Clinically relevant Alzheimer's disease co‐pathology is common in Lewy body disorders. Plasma P‐tau217 is a sensitive biomarker for amyloid and tau pathology in Alzheimer's disease. The objective was to determine if plasma P‐tau217 associates with Alzheimer's disease co‐pathology and cognition in Lewy body disorders. Methods Participants had (

AI‐Driven Mapping of Seizure Spread Patterns

Annals of Neurology, EarlyView.
Objective The focus of epilepsy research has largely been on seizure onset; however, physicians typically examine the patterns of seizure spread past seizure onset as well. This study aims to align automated seizure analysis with clinical practice, leverage deep learning to standardize seizure annotations that varies among physicians, and understand ...

T. rex cognition was T. rex‐like—A critical outlook on diverging views of the neurocognitive evolution in dinosaurs

The Anatomical Record, EarlyView.
Abstract A recent debate has emerged between Caspar et al. (2024) and Herculano‐Houzel (2023) on inferring extinct dinosaur cognition by estimating brain neuron counts. While thought‐provoking, the discussion largely overlooks the function of cognition, as well as partly neglects the difficulties involved in estimating neuron numbers, which according ...

Localist but Distributed Representations [PDF]

, 1999
A number of examples are given of how localist models may incorporate distributed representations, without the types of non-local interactions that often render distributed models implausible.

Endothermy, neuron counts, and other issues: Further remarks on neurocognitive evolution in fossil vertebrates

The Anatomical Record, EarlyView.
Abstract Last year, we challenged the view that large‐bodied theropod dinosaurs such as Tyrannosaurus rex resembled primates in cognition and behavior, a proposition made by Herculano‐Houzel in 2023. More recently, Jensen et al. have criticized our work on this topic, raising methodological and conceptual issues.

The E3 Ubiquitin Ligase UBE3B Regulates Synaptic Development and Cortical Network Activity

Autism Research, EarlyView.
ABSTRACT Autism spectrum disorder (ASD) is a neurodevelopmental disorder characterized by impaired communication, abnormal social interactions, and restricted, repetitive behaviors. Pathogenic mutations in UBE3B result in neurodevelopmental disease, including intellectual disability, lack of speech, and ASD.
