|August 19, 2017
Summary
Acute exercise enhances cognition by increasing brain-derived neurotrophic factor (BDNF), influenced by cerebral blood flow and oxidative stress. Understanding these mechanisms can aid recovery in clinical populations and support healthy aging.
Area of Science:
- Neuroscience
- Exercise Physiology
Background:
- Cognitive enhancement after exercise is not fully understood.
- Brain-derived neurotrophic factor (BDNF) is a proposed key mediator.
Purpose of the Study:
- To investigate the role of BDNF in exercise-induced cognitive improvement.
- To explore the influence of cerebral blood flow (CBF) and oxidative stress on BDNF release from cerebral endothelial cells.
Main Methods:
- Hypothesize that blocking endothelial function will affect BDNF levels and cognitive performance.
- Propose using multiple linear regression to examine relationships between CBF, oxidative stress, BDNF, and cognition.
Main Results:
- The study outlines hypotheses to be tested, not yet presenting empirical results.
- Expected results include linear relationships between CBF+oxidative stress and BDNF, and between BDNF and cognitive performance.
Conclusions:
- The research emphasizes the cerebral endothelium's role in exercise-cognition links.
- Findings could guide strategies to optimize BDNF release for cognitive enhancement and clinical recovery.

01:01Neuroplasticity
2.0K
Neuroplasticity reflects the brain's remarkable capacity to adapt and evolve, responding dynamically to learning, experiences, or injury by reorganizing its neural circuitry. This reorganization involves creating new neural connections and refining old ones through a series of biological processes that contribute to the brain's lifelong development and adaptability.

58.9K
Long-term potentiation, or LTP, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTP is the process of synaptic strengthening that occurs over time between pre- and postsynaptic neuronal connections. The synaptic strengthening of LTP works in opposition to the synaptic weakening of long-term depression (LTD) and together are the main mechanisms that underlie learning and memory.

01:15Neurogenesis and Regeneration of Nervous Tissue
1.8K
In the CNS, neurogenesis, the birth of new neurons from stem cells, is limited to the hippocampus in adults. In other regions of the brain and spinal cord, neurogenesis is almost non-existent due to inhibitory influences from neuroglia, especially oligodendrocytes, and the absence of growth-stimulating cues. The myelin produced by oligodendrocytes in the CNS inhibits neuronal regeneration. Furthermore, astrocytes proliferate rapidly after neuronal damage, forming scar tissue that physically...

01:30Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists
718
Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function.
