Espinas dendríticas: una ventana al estudio de la plasticidad neuronal

Jóvenes en la ciencia
El propósito de este artículo es realizar una revisión breve acerca de las espinas dendríticas neuronales: estructuras que se conocen por ser sitios importantes en la comunicación y en la plasticidad sináptica. Se aborda su descubrimiento gracias a la técnica de tinción desarrollada por Camilo Golgi, las diversas formas que pueden adoptar y su función;

Maltrato infantil, alteraciones en eje hipotálamo-hipofisis-suprarreral: Impacto en crecimiento y plasticidad neuronal

Acta Pediatrica De Mexico
El maltrato infantil es un problema de salud pública con efectos inmediatos y prolongados en el desarrollo físico, emocional y neurobiológico en los niños. Se define como cualquier forma de abuso o desatención que afecte a un menor de 18 años e incluye abuso físico, emocional, sexual, negligencia y explotación este mismo tiene un impacto en el ...

Oligodendrocyte origin and development in the zebrafish visual system

Journal of Comparative Neurology, Volume 531, Issue 4, Page 515-527, March 2023., 2023
Graphical Abstract The first oligodendrocyte progenitor cells (OPCs, olig2:EGFP/Sox2, yellow cells) are detected in the preoptical area of the hypothalamus at 2 dpf. One day later, 3 dpf, these cells invade the optic chiasm and colonize the postchiasmatic region first and the prechiasmatic later (yellow cells). As they differentiate to oligodendrocytes,

The serum metabolome mediates the concert of diet, exercise, and neurogenesis, determining the risk for cognitive decline and dementia

Alzheimer's &Dementia, Volume 18, Issue 4, Page 654-675, April 2022., 2022
Abstract Introduction Diet and exercise influence the risk of cognitive decline (CD) and dementia through the food metabolome and exercise‐triggered endogenous factors, which use the blood as a vehicle to communicate with the brain. These factors might act in concert with hippocampal neurogenesis (HN) to shape CD and dementia. Methods Using an in vitro

Kainate receptor modulation of glutamatergic synaptic transmission in the CA2 region of the hippocampus

Journal of Neurochemistry, Volume 158, Issue 5, Page 1083-1093, September 2021., 2021
Kainate receptors (KARs) located in hippocampal CA3 neurons contacting CA2 pyramidal cells mediate a decrease in glutamate release. This depression of glutamate release requires Gi/o protein and protein kinase A (PKA) signaling. This is the first time KARs have been described in the CA2 region of the hippocampus.

Corporeidade, Movimento, Plasticidade Neuronal e Maturidade Ativa

Estudos Interdisciplinares sobre o Envelhecimento, 2001
Resumo: Nos dias de hoje existe uma perda das referências do indivíduo como alguém possuidor de qualidades únicas. A padronização de gestos e condutas faz com que muitos não reconheçam suas sensações como legítimas buscando-se adequar a um modelo dos Meios de Comunicação Social (MCS).

Impaired Cerebral Vasomotor Reactivity in Alzheimer’s Disease

International Journal of Alzheimer’s Disease, Volume 2018, Issue 1, 2018., 2018
Background. Recent studies have shown that cerebral vascularity may be impaired in Alzheimer’s disease. Cerebral vasomotor reactivity could be an important biomarker for this pathology. Aims. The aim of this study was to investigate the alterations in cerebral vascular motor reactivity in Alzheimer’s disease subjects and to associate these changes with

Integrated Stress Response as a Therapeutic Target for CNS Injuries

BioMed Research International, Volume 2017, Issue 1, 2017., 2017
Central nervous system (CNS) injuries, caused by cerebrovascular pathologies or mechanical contusions (e.g., traumatic brain injury, TBI) comprise a diverse group of disorders that share the activation of the integrated stress response (ISR). This pathway is an innate protective mechanism, with encouraging potential as therapeutic target for CNS injury

Programming of Dopaminergic Neurons by Neonatal Sex Hormone Exposure: Effects on Dopamine Content and Tyrosine Hydroxylase Expression in Adult Male Rats

Neural Plasticity, Volume 2016, Issue 1, 2016., 2016
We sought to determine the long‐term changes produced by neonatal sex hormone administration on the functioning of midbrain dopaminergic neurons in adult male rats. Sprague‐Dawley rats were injected subcutaneously at postnatal day 1 and were assigned to the following experimental groups: TP (testosterone propionate of 1.0 mg/50 μL); DHT ...
