Development of a Conditional Generative Adversarial Network Model for Television Spectrum Radio Environment Mapping

IEEE Access
To efficiently use the finite wireless communication resource (radio spectrum), a Radio Environment Map (REM) is needed to monitor, analyse and provide rich awareness of spectrum activities in a radio propagating environment.

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 ...

Timing is everything: The effect of early‐life seizures on developing neuronal circuits subserving spatial memory

Epilepsia Open, EarlyView.
Abstract Spatial memory, the aspect of memory involving encoding and retrieval of information regarding one's environment and spatial orientation, is a complex biological function incorporating multiple neuronal networks. Hippocampus‐dependent spatial memory is not innate and emerges during development in both humans and rodents.

Exploring Linalool‐Based Phytotherapy for Excitatory/Inhibitory Imbalance in Alzheimer's Disease: A Review of Lavender and Cannabis Therapeutic Effects on Sleep, Seizures, and Cognition

Phytotherapy Research, EarlyView.
Schematic overview of the proposed neuromodulatory actions of linalool in Alzheimer's disease. Through multi‐target effects on oxidative stress, amyloid aggregation, GABAergic and glutamatergic signaling, linalool may restore excitatory/inhibitory balance.
