neuroscience papers | Gist.Science

Neuroscience explores the intricate machinery of the brain and nervous system, seeking to understand how we think, feel, and move. From the microscopic dance of individual neurons to the complex networks that shape our memories and behaviors, this field peels back the layers of our biological selves to reveal the origins of consciousness and disease.

At Gist.Science, we bring these discoveries directly from bioRxiv, the leading preprint server for biological sciences, to a broader audience. We process every new neuroscience preprint as it is uploaded, transforming dense academic manuscripts into clear, plain-language explanations alongside detailed technical summaries. This ensures that both curious readers and specialists can stay current with the latest breakthroughs before they are formally published.

Below are the latest neuroscience papers we have processed from bioRxiv, offering fresh insights into the workings of the mind.

Comparison of Alternative pre-mRNA Splicing and Gene Expression Patterns in Midbrain Lineage Cells Carrying Familial Parkinson's Disease Mutations

This study analyzes global gene expression and pre-mRNA splicing patterns in midbrain lineage cells derived from human pluripotent stem cells carrying 12 distinct familial Parkinson's disease mutations, revealing mutation-specific splicing changes linked to key cellular defects that overlap with postmortem brain findings and may serve as diagnostic biomarkers or therapeutic targets.

Gut distension evokes rapid neural dynamics in vagal and hindbrain populations of larval zebrafish

This study demonstrates that in larval zebrafish, gut distension and aversive chemical cues are rapidly encoded by distinct temporal dynamics in vagal and hindbrain neurons, revealing that fast gut-to-brain communication emerges early in life to regulate nutrient-specific feeding.

Opposite Effects of Alpha Oscillations on Mind-Wandering With Eyes Open and Closed

This study resolves conflicting findings on the relationship between alpha oscillations and mind-wandering by demonstrating that the effect of alpha power reverses depending on eye state, with higher alpha predicting increased mind-wandering when eyes are open but decreased mind-wandering when eyes are closed.

Punctuated memory change: The temporal dynamics and brain basis of memory stability in aging

Analyzing 728,000 memory tests from 80,000 participants, this study reveals that while a small minority of older adults maintain stable episodic memory linked to preserved brain structure, most experience cognitive aging as a complex system characterized by long periods of stability punctuated by sudden, critical transitions of accelerated decline rather than continuous erosion.

Unique and overlapping behavioral effects of isoform-specific NRXN1 deletions across development

This study demonstrates that zebrafish models with isoform-specific deletions of the *nrxn1a* gene exhibit distinct yet overlapping behavioral deficits, supporting a model where specific *NRXN1* isoform disruptions predict particular neuropsychiatric phenotypes.

Gut microbial diversity and inferred capacity to produce short-chain fatty acids are tied to acute stress reactivity in healthy adults

This study demonstrates that in healthy adults, higher gut microbial alpha diversity and the inferred capacity to produce short-chain fatty acids are associated with increased acute stress reactivity, as measured by cortisol levels and subjective stress.

Respiration as a dynamic modulator of sensory sampling

This study demonstrates that respiration dynamically modulates human sensory perception by orchestrating brain states and arousal levels, where aligning breathing patterns with predictable stimuli enhances perceptual sensitivity through optimized information flow within interoceptive networks.

Implications of recursive Bayesian Sensory Inference

This study uses a recursive Bayesian computational model to demonstrate that the relative weighting of velocity-based versus position-based proprioceptive feedback critically influences state estimation and endpoint errors in motor control, revealing that different internal sensory assumptions can produce similar observable behaviors in some experimental conditions while diverging significantly in others.

When Velocity Becomes Position: Proprioceptive Contributions to State Estimation

This study demonstrates through virtual reality experiments and Bayesian computational modeling that, in the absence of visual feedback, the human brain relies heavily on velocity-based proprioceptive cues rather than absolute positional information for state estimation, resulting in slow corrections to visual perturbations during movement.

The Vesicular Glutamate Transporter Modulates Sex and Region-Specific Differences in Dopaminergic Neuron α-Synuclein Toxicity by Modifying Cytosolic Dopamine Levels

This study demonstrates that lower levels of the vesicular glutamate transporter in female *Drosophila* dopamine neurons reduce cytosolic dopamine sequestration, thereby increasing cytosolic dopamine levels and susceptibility to $\alpha$ -synuclein toxicity, which explains the sex-specific vulnerability to Parkinson's disease-like neurodegeneration observed in males.
