Summary
Higher reward sensitivity in males is linked to smaller gray matter volume in brain regions like the dorsal striatum. This suggests reduced striatal volume may correlate with enhanced reward sensitivity and impaired inhibitory control.
Area of Science:
- Neuroscience
- Neuroimaging
- Behavioral Science
Background:
- The brain's reward system plays a crucial role in motivation and behavior.
- Understanding the neural correlates of reward sensitivity is important for various psychological conditions.
Purpose of the Study:
- To investigate the relationship between brain structure and reward sensitivity in male undergraduates.
- To explore the association between gray matter volume in reward-related brain areas and scores on the Sensitivity to Reward scale.
Main Methods:
- Optimized voxel-based morphometry (VBM) was employed to analyze brain structure.
- Gray matter volume was correlated with scores from the Sensitivity to Reward scale in 50 male undergraduates.
Main Results:
- A significant negative correlation was found between Sensitivity to Reward scores and gray matter volume.
- This association was observed in the dorsal striatum and prefrontal cortex.
Conclusions:
- Reduced gray matter volume in the dorsal striatum may be associated with heightened reward sensitivity.
- Findings suggest a potential link between striatal volume, reward sensitivity, and deficits in inhibitory control.

01:30Attention-Deficit/Hyperactivity Disorder
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings.

01:13Functional Brain Systems: Reticular Formation
The reticular formation is a complex network of gray and white matter located within the brainstem extending from the medulla to the midbrain.
Within the reticular formation, there are several distinct nuclei that can be classified into three broad categories. The Raphe nuclei are located along the midline of the brainstem. They are primarily known for their role in synthesizing and releasing serotonin, a neurotransmitter involved in regulating mood, appetite, sleep, and circadian rhythms. The...

01:16Sympathetic Activation
The sympathetic division can influence tissues and organs by releasing norepinephrine at peripheral synapses and distributing epinephrine and norepinephrine through the bloodstream. In times of crisis or stress, sympathetic activation occurs, which is regulated by sympathetic centers in the hypothalamus. As a result, sympathetic activation prepares the body for physical exertion, rapid ATP production, and heightened alertness, allowing individuals to respond effectively to challenging or...
01:37Neural 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.
01:15Functional 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...
01:28Causes of Social Behavior III: Biological and Environmental Influences
Social behavior is a complex phenomenon that arises from the interaction between biological predispositions and environmental influences. This intricate interplay shapes how individuals think, feel, and act in various social contexts. Understanding these mechanisms requires insights from psychology, neuroscience, genetics, and evolutionary theory.Environmental Influences on Social BehaviorEnvironmental factors, including temperature, odors, and visual stimuli, play a crucial role in shaping...
