Diencephalon: Anatomical Regions

Diencephalon: Anatomical Regions

The diencephalon, etymologically translated as 'through brain,' plays an integral role as the conduit between the cerebrum and the vast extent of the nervous system. However, the olfactory system is an exception, as it interfaces directly with the cerebrum. The diencephalon, deeply ensconced beneath the cerebrum, primarily consists of three paired structures — the thalamus, hypothalamus, and epithelamus. It also includes accessory structures such as the subthalamus, which houses the...

Functional Brain Systems: Limbic System

Functional Brain Systems: Limbic System

The limbic system, often called the "emotional brain," is a complex set of structures located deep within the brain. The intricate network of the limbic system supports a wide range of psychological functions, from emotional regulation to memory formation and sensory processing. This functional brain region encompasses specific parts of the diencephalon and the cerebrum, integrating the higher mental functions of the cerebral cortex with the primitive emotional responses of the deep brain...

The Influence of Affect on Cognition

The Influence of Affect on Cognition

Positive affect significantly influences cognitive processes, including evaluation, memory, creativity, and social judgments. Compared to negative affect, positive emotional states promote more favorable interpretations of stimuli, cognitive flexibility, and heuristic processing. These effects highlight emotions' powerful role in shaping how individuals perceive, remember, and interact with the world.Influence on Evaluation and AttributionWhen individuals experience positive affect, they are...

Neural Regulation

Neural Regulation

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.

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...

Negative and Cognitive Symptoms of Schizophrenia

Negative and Cognitive Symptoms of Schizophrenia

Negative symptoms of schizophrenia indicate a reduction or absence of typical behaviors and emotional responses found in healthy individuals, while positive symptoms reflect an excess or distortion of normal functioning.
Negative Symptoms
Negative symptoms of schizophrenia manifest as deficits in normal emotional and behavioral functioning, profoundly impacting daily life. Individuals with schizophrenia often display a flat affect, characterized by a near-total absence of emotional expression,...

Area of Science:

Neuroscience
Psychiatry
Molecular Biology

Background:

The lateral habenula (LHb) is a critical brain region involved in major depressive disorder (MDD) pathophysiology.
Hyperactivity of excitatory LHb neurons in MDD leads to suppressed reward signaling via downstream pathways.

Purpose of the Study:

To review current knowledge on inhibitory signaling mechanisms within the LHb.
To explore the therapeutic potential of targeting these mechanisms for MDD treatment.

Main Methods:

This article is a review of existing scientific literature.
It synthesizes findings on neural circuits and pharmacology related to LHb inhibitory signaling.

Main Results:

Aberrant inhibitory signaling onto LHb neurons is implicated as a co-causative factor in MDD.
Dysregulation of inhibitory signaling may lead to disinhibition of excitatory neurons.

Conclusions:

Normalizing inhibitory signaling in the LHb presents a promising therapeutic strategy for MDD.
Further research is needed to fully elucidate the pharmacological and circuit mechanisms controlling LHb inhibitory signaling.
