Whole-brain drug distribution profiles of psychedelic drugs provide insights into rapid antidepressant action

By integrating pharmacodynamic profiles with receptor density data from PET and autoradiography, this study maps the whole-brain distribution of classic hallucinogens and ketamine, revealing that their rapid antidepressant effects are driven by strong action in emotion-processing regions, particularly association cortices and supragranular layers.

Integrated metabolomics and proteomics from voxelated cortical hemispheres of adult rhesus monkeys

This study establishes a framework for generating spatially registered, paired metabolomic and proteomic maps across entire rhesus monkey cortical hemispheres at millimeter resolution, utilizing novel computational algorithms to reveal conserved molecular gradients and reconstruct complete metabolic circuits that reflect spatially organized biological variance.

HeteroRC: Decoding latent information from dynamic neural responses with interpretable heterogeneous reservoir computing

The paper introduces HeteroRC, a biologically inspired and interpretable heterogeneous reservoir computing framework that outperforms conventional linear decoders and complex neural networks by effectively extracting latent nonlinear, non-phase-locked, and "activity-silent" information from dynamic neural responses without requiring manual feature engineering.

PINN-ing the Balloon: A Physically Informed Neural Network Modelling the Nonlinear Haemodynamic Response Function in MRI

This paper introduces a physics-informed neural network framework that integrates the Balloon-Windkessel model into its training objective to accurately estimate latent neurovascular state variables and generate subject-specific haemodynamic response functions from fMRI data, overcoming the limitations of traditional phenomenological approaches.

Insulin Growth Factor 1 affects glutamate receptor activity differently in primary cultures of neocortical versus hippocampal neurons

This study demonstrates that Insulin-like Growth Factor 1 (IGF-1) exerts region-specific effects on glutamate receptor activity by inhibiting AMPA receptor-mediated calcium responses in neocortical neurons while enhancing them in hippocampal neurons, suggesting a potential neuroprotective role against excitotoxicity in the neocortex that may be compromised in conditions like insulin resistance.

Redox imbalance dictates dependence on GOT1 versus GOT2 for rod photoreceptor health during aging and stress

This study reveals that rod photoreceptor health critically depends on the cytosolic enzyme GOT1 to prevent toxic NADH accumulation, whereas the mitochondrial enzyme GOT2 is downregulated during stress as a protective mechanism, identifying reductive stress as a key driver of degeneration and GOT2 as a novel therapeutic target.

Acute exposure of mouse and human hippocampal slices to tau oligomers reversibly impairs sharp-wave ripples

This study demonstrates that acute exposure to beta-sheet-containing tau oligomers reversibly impairs sharp-wave ripple oscillations in both mouse and human hippocampal slices, with species-specific effects on ripple parameters, establishing a high-throughput ex vivo model for investigating Alzheimer's disease mechanisms and screening therapeutics.
