Role of Neurotransmitters in Memory01:23

Role of Neurotransmitters in Memory

2.9K
Neurotransmitters are integral to the brain's communication system, enabling neurons to transmit signals across synapses. This chemical exchange underpins various cognitive functions, including memory processes. The role of neurotransmitters in memory is multifaceted, influencing the encoding, consolidation, and retrieval of memories through their action on different neural circuits.

Neural Regulation01:37

Neural Regulation

44.6K
Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Disorders of the Nervous Tissue

3.0K
Nervous tissue is a vital component of the human body's communication system, enabling us to perceive and respond to stimuli. However, like all other tissues, it is vulnerable to disorders and diseases that can significantly impact our neurological functioning.

Alzheimer's disease manifests as a gradual decline in memory and cognitive abilities, attributed to the buildup of amyloid plaques and neurofibrillary tangles in the brain.

Alzheimer's Disease: Overview

2.0K
Alzheimer's Disease (AD) is a continually advancing neurodegenerative disorder, distinguished by escalating memory loss, cognitive dysfunction, and dementia. The disease unfolds in three stages: preclinical, mild cognitive impairment (MCI), and dementia. Its onset is insidious, and the progression gradual, with the cause not well explained by other disorders.
The clinical diagnosis of AD hinges on the presence of memory and other cognitive impairments. Biomarkers, such as changes in Aβ...

Long-term Depression01:03

Long-term Depression

3.5K
Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Necrosis01:16

Necrosis

7.2K
Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become...

Area of Science:

  • Neuroscience
  • Toxicology
  • Biochemistry

Background:

  • Metals are essential for cellular functions, including gene expression and neurotransmission.
  • However, excessive metal accumulation in the nervous system can lead to toxicity.
  • This toxicity can manifest as oxidative stress, mitochondrial dysfunction, and enzyme inhibition.

Purpose of the Study:

  • To survey the existing literature on the role of metals in neurodegeneration.
  • To highlight the link between aberrant metal exposure and neurological diseases.

Main Methods:

  • Literature review of epidemiological and clinical studies.
  • Analysis of research on metal accumulation and neurotoxicity.

Main Results:

  • A strong correlation exists between aberrant metal exposure and neurodegenerative diseases.
  • Specific diseases linked include Alzheimer's, Parkinson's, and multiple sclerosis.

Conclusions:

  • Metals play a dual role in the human body, being essential in trace amounts but toxic in excess.
  • Understanding metal's role in neurodegeneration is crucial for developing therapeutic strategies for neurological disorders.
