Disorders of the Nervous Tissue01:28

Disorders of the Nervous Tissue

1.5K
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.
Homeostatic Imbalances:
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.

Psychoneuroimmunology: Cardiovascular Disease

71
Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...

Role of Neurotransmitters in Memory01:23

Role of Neurotransmitters in Memory

934
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.

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders

916
Schizophrenia is a neurodevelopmental disorder whose origins are rooted in complex genetic components. Despite our burgeoning understanding, the pathophysiology of this disorder remains incompletely deciphered.
Researchers have identified genetic factors that increase susceptibility to schizophrenia, underscoring the intricate interplay between genetics and environment in disease development. At the core of schizophrenia's pathophysiology is excessive dopaminergic neurotransmission within...

Introduction to Biological Bases of Psychology

3.5K
Biopsychology serves as a vital bridge connecting the intricate domains of biology and psychology, shedding light on how biological systems influence psychological phenomena. This field scrutinizes the biological substrates of behavior and mental processes, emphasizing the nervous system along with the roles of neurotransmitters, hormones, and genetics. It also incorporates evolutionary perspectives to explain the adaptive nature of mental functions.
The nervous system, the cornerstone of...

Area of Science:

  • Neuroscience
  • Immunology
  • Psychiatry

Background:

  • Cognitive dysfunction is a key symptom in many psychiatric disorders.
  • Brain-immune system interactions are known to influence cognitive function.
  • The precise mechanisms linking immune responses to brain changes in cognitive decline remain largely unknown.

Purpose of the Study:

  • To review and synthesize current research on brain-immune interaction mechanisms underlying cognitive decline.
  • To clarify the role of neuro-immune pathways in psychiatric disorders associated with cognitive impairment.

Main Methods:

  • Systematic review of relevant scientific literature.
