Anatomical organization of temporally correlated neural calcium activity in the hippocampal CA1 region

iScience, 2023
Summary: Hippocampal CA1 neuronal ensembles generate sequential patterns of firing activity that contribute to episodic memory formation and spatial cognition. Here we used in vivo calcium imaging to record neural ensemble activities in mouse hippocampal

Memory rescue and learning in synaptic impaired neuronal circuits

iScience, 2023
Summary: Neuronal impairment is a characteristic of Alzheimer’s disease (AD), but its effect on neural activity dynamics underlying memory deficits is unclear.

Psychoanalysis and neurosciences: fuzzy outlines? Notes on the notion of cerebral plasticity [PDF]

, 2017
“Psychoanalysis versus psychiatry” and “unconscious versus brain” are classic oppositions between different perspectives on the human being and mental suffering.

Identification and development of TRPM4 antagonists to counteract neuronal excitotoxicity

iScience
Summary: Neurodegeneration in central nervous system disorders is linked to dysregulated neuronal calcium. Direct inhibition of glutamate-induced neuronal calcium influx, particularly via N-methyl-D-aspartate receptors (NMDAR), has led to adverse effects

Semaphorin 6A–Plexin A2/A4 Interactions with Radial Glia Regulate Migration Termination of Superficial Layer Cortical Neurons

iScience, 2019
Summary: Precise regulation of neuronal migration termination is crucial for the establishment of brain cytoarchitectures. However, little is known about how neurons terminate migration.

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 ...

Reduction of prefrontal purinergic signaling is necessary for the analgesic effect of morphine

iScience, 2021
Summary: Morphine is commonly used to relieve moderate to severe pain, but repeated doses cause opioid tolerance. Here, we used ATP sensor and fiber photometry to detect prefrontal ATP level.

The Accumulation of Tau-Immunoreactive Hippocampal Granules and Corpora Amylacea Implicates Reactive Glia in Tau Pathogenesis during Aging

iScience, 2020
Summary: The microtubule-associated tau protein forms pathological inclusions that accumulate in an age-dependent manner in tauopathies including Alzheimer's disease (AD). Since age is the major risk factor for AD, we examined endogenous tau species that

FEZ1 participates in human embryonic brain development by modulating neuronal progenitor subpopulation specification and migrations

iScience, 2023
Summary: Mutations in the human fasciculation and elongation protein zeta 1 (FEZ1) gene are found in schizophrenia and Jacobsen syndrome patients. Here, using human cerebral organoids (hCOs), we show that FEZ1 expression is turned on early during brain ...

SUR1 Receptor Interaction with Hesperidin and Linarin Predicts Possible Mechanisms of Action of Valeriana officinalis in Parkinson. [PDF]

, 2016
Parkinson's disease (PD) is one of the most common neurodegenerative disorders. A theoretical approach of our previous experiments reporting the cytoprotective effects of the Valeriana officinalis compounds extract for PD is suggested.
