Descending pathways increase sensory neural response heterogeneity to facilitate decoding and behavior

iScience, 2023
Summary: The functional role of heterogeneous spiking responses of otherwise similarly tuned neurons to stimulation, which has been observed ubiquitously, remains unclear to date.

Corticosterone antagonist or TrkB agonist attenuates schizophrenia-like behavior in a mouse model combining Bdnf-e6 deficiency and developmental stress

iScience, 2022
Summary: While schizophrenia pathogenesis involves both genetic and environmental factors, their specific combinations remain ill-defined. Here we show that deficiency in promoter VI-driven BDNF expression, combined with early-life adversity, results in ...

Autonomous Reinforcement of Behavioral Sequences in Neural Dynamics [PDF]

, 2012
We introduce a dynamic neural algorithm called Dynamic Neural (DN) SARSA(\lambda) for learning a behavioral sequence from delayed reward. DN-SARSA(\lambda) combines Dynamic Field Theory models of behavioral sequence representation, classical ...

Unsupervised discovery of temporal sequences in high-dimensional datasets, with applications to neuroscience. [PDF]

, 2019
Identifying low-dimensional features that describe large-scale neural recordings is a major challenge in neuroscience. Repeated temporal patterns (sequences) are thought to be a salient feature of neural dynamics, but are not succinctly captured by ...

Higher oxytocin concentrations occur in subjects who build affiliative relationships with companion robots

iScience, 2023
Summary: Building affiliative relationships with others is important for mental health. Recently, robots have been expected to play a role in improving mental health, but there is little scientific evidence as to whether they can build affiliative ...

Electroencephalography (EEG)-Derived Markers to Measure Components of Attention Processing [PDF]

, 2017
Although extensively studied for decades, attention system remains an interesting challenge in neuroscience field. The Attention Network Task (ANT) has been developed to provide a measure of the efficiency for the three attention components ...

Drosophila Aversive Behavior toward Erwinia carotovora carotovora Is Mediated by Bitter Neurons and Leukokinin

iScience, 2020
Summary: The phytopathogen Erwinia carotovora carotovora (Ecc) has been used successfully to decipher some of the mechanisms that regulate the interactions between Drosophila melanogaster and bacteria, mostly following forced association between the two ...

Curation of microarray oligonucleotides and corresponding ESTs/cDNAs used for gene expression analysis in zebra finches

BMC Research Notes, 2018
Objectives Zebra finches are a major model organism for investigating mechanisms of vocal learning, a trait that enables spoken language in humans. The development of cDNA collections with expressed sequence tags (ESTs) and microarrays has allowed for ...

Convergence of location, direction, and theta in the rat anteroventral thalamic nucleus

iScience, 2023
Summary: The thalamus and cortex are anatomically interconnected, with the thalamus providing integral information for cortical functions. The anteroventral thalamic nucleus (AV) is reciprocally connected to retrosplenial cortex (RSC).

Great nature’s second course: Introduction to the special issue on the behavioral neuroscience of sleep [PDF]

, 2016
Sleep is necessary for normal psychological functioning, and psychological function in turn affects sleep integrity. Recent investigations delineate the relation of sleep to a broad array of processes ranging from learning and memory to emotional ...
