Long-term Depression

Long-term Depression

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.

Role of Neurotransmitters in Memory

Role of Neurotransmitters in Memory

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.

Excitatory and Inhibitory Effects of Neurotransmitters

Excitatory and Inhibitory Effects of Neurotransmitters

When an action potential reaches the presynaptic axon terminal, it releases neurotransmitters from the neuron into the synaptic cleft at a chemical synapse. The released neurotransmitter can be excitatory or inhibitory. The critical criteria commonly used to determine whether a molecule is a neurotransmitter at a chemical synapse are the molecule's presence in the presynaptic neuron. Second, its release is in response to strong presynaptic depolarization. And lastly, the presence of specific...

Disorders of the Nervous Tissue

Disorders of the Nervous Tissue

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.
Parkinson's disease arises from the...

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders

Psychosis: Pathophysiology of Schizophrenia and Other Psychotic Disorders

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 the...

Background:

Central nervous system (CNS) disorders often present with complex etiologies involving genetics, epigenetics, and environmental factors.
Despite diverse causes, many CNS disorders exhibit converging deficits in memory function.
Advances in genomics reveal significant genetic heterogeneity contributing to neuronal pathologies in CNS disorders.

Purpose of the Study:

To propose a unifying mechanism for the development of various CNS disorders.
To explore the role of abnormal dendritic integration of synaptic signals in CNS pathophysiology.
To link molecular genetics and cellular neurophysiology to network-level dysfunctions and memory impairments.

Main Methods:

This is a review article, synthesizing existing research.
It focuses on the integration of molecular genetics, dendritic computation, and network abnormalities.
The review examines how synaptic signal integration impacts neuronal function and behavior.

Main Results:

The review posits that abnormal dendritic integration is a common pathway in CNS disorders.
This cellular-level dysfunction may underlie higher-order circuit and network abnormalities.
Understanding this link can illuminate the basis of memory deficits in CNS disorders.

Conclusions:

Abnormal dendritic integration of synaptic signals is proposed as a fundamental mechanism in many CNS disorders.
Future research should focus on the interplay between molecular genetics and dendritic computation.
This approach may reveal critical links between cellular neurophysiology and CNS disorder manifestations, particularly memory dysfunction.
