Cortical and subcortical somatosensory regulation of dopaminergic neurons: role of the superior colliculus [PDF]

open access: yes, 2011
Dopaminergic (DA) neurons exhibit a short-latency, phasic response to unexpected biologically salient stimuli, including rewards. Despite extensive research on this DA signal, very little is known about the sources of sensory ...

The Influence of the Number of Spiking Neurons on Synaptic Plasticity

open access: yesBiomimetics, 2023
The main advantages of spiking neural networks are the high biological plausibility and their fast response due to spiking behaviour. The response time decreases significantly in the hardware implementation of SNN because the neurons operate in parallel.

Volume, neuron density and total neuron number in five subcortical regions in schizophrenia [PDF]

open access: yesBrain, 2007
Several studies have pointed to alterations in mean volumes, neuron densities and total neuron numbers in the caudate nucleus (CN), putamen, nucleus accumbens (NA), mediodorsal nucleus of the thalamus (MDNT) and lateral nucleus of the amygdala (LNA) in schizophrenia.

Nuclear expression of PG-21, SRC-1, and pCREB in regions of the lumbosacral spinal cord involved in pelvic innervation in young adult and aged rats [PDF]

open access: yes, 2012
In rats, ageing results in dysfunctional patterns of micturition and diminished sexual reflexes that may reflect degenerative changes within spinal circuitry.

Decoder accuracy as a function of number of neurons.

open access: yes, 2021
Decoder accuracy for both image change (black) and image identity (red) increases with the number of neurons included in the analysis, saturating around 100 neurons.

Constraints of Metabolic Energy on the Number of Synaptic Connections of Neurons and the Density of Neuronal Networks [PDF]

open access: yesFrontiers in Computational Neuroscience, 2018
Neuronal networks in the brain are the structural basis of human cognitive function, and the plasticity of neuronal networks is thought to be the principal neural mechanism underlying learning and memory. Dominated by the Hebbian theory, researchers have devoted extensive effort to studying the changes in synaptic connections between neurons.

The human gut microbiome across the life course

open access: yesFEBS Letters, EarlyView.
Despite significant individual variation and continuous change throughout life, the human gut microbiome follows some life stage‐specific trends. This article provides a brief overview of how gut microbiome composition shifts across different phases of life. Created in BioRender. Özkurt, E. (2026) https://BioRender.com/8q4nrnc.
