Autism Spectrum Disorder01:19

Autism Spectrum Disorder

1.7K
Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

Modeling in Therapy01:26

Modeling in Therapy

708
Modeling, a key technique in therapy, uses observational learning to help clients acquire and practice new skills by watching therapists demonstrate desired behaviors. This approach, rooted in Albert Bandura's concept of vicarious learning, plays a significant role in therapeutic interventions for various psychological conditions, including social anxiety, ADHD, and depression.

Operant Conditioning Intervention01:24

Operant Conditioning Intervention

655
Operant conditioning serves as a foundational principle in therapeutic interventions aimed at modifying maladaptive behaviors. Central to this approach is the notion that behaviors, both adaptive and maladaptive, are learned through reinforcement. By analyzing the environmental factors that reinforce problematic behaviors, clinicians can design interventions to weaken these reinforcements and replace maladaptive behaviors with healthier alternatives.
In operant conditioning, behaviors that are...

Social Anxiety Disorder01:28

Social Anxiety Disorder

770
Social anxiety disorder, also known as social phobia, is characterized by an intense fear of social situations where one might face humiliation, rejection, embarrassment, or negative evaluation. This disorder leads individuals to avoid activities like casual conversations, public speaking, or seemingly simple tasks such as eating, signing documents, or swimming, in public settings. Its impact extends beyond discomfort, often significantly interfering with daily functioning and quality of life.

Antisocial Personality Disorder01:24

Antisocial Personality Disorder

1.2K
Antisocial personality disorder is a chronic mental health condition characterized by persistent patterns of disregard for the rights and well-being of others. Individuals with antisocial personality disorder exhibit behaviors that include deceitfulness, impulsivity, irresponsibility, aggression, and a profound lack of empathy. These traits often manifest early in life and persist into adulthood, leading to significant personal, social, and legal consequences.

Behavior Modification

948
Behavioral approaches have often been criticized for ignoring mental processes and focusing solely on observable behavior. However, these approaches provide an optimistic perspective for individuals seeking to change their behaviors. Rather than concentrating on intrinsic personality traits, behavioral approaches suggest that even longstanding habits can be modified by changing the reward contingencies that maintain them.
A real-world application of operant conditioning principles is applied...

Area of Science:

  • Neuroscience
  • Developmental Neuroscience
  • Neuroimaging

Background:

  • Autism spectrum disorder (ASD) is characterized by social communication deficits.
  • The social brain, comprising reward, theory of mind, mirror neuron, and face perception networks, is implicated in social information processing.
  • Neural mechanisms and modular integration within the social brain in ASD remain unclear.

Purpose of the Study:

  • To investigate abnormal modular integration within the social brain networks in individuals with ASD.
  • To explore associations between altered social brain integration and clinical symptoms, neurotransmitters, and transcriptional signatures.
  • To assess the developmental stability and reproducibility of findings in ASD.

Main Methods:

  • Utilized resting-state functional MRI (rs-fMRI) data from the ABIDE I and II datasets.
  • Calculated the participation coefficient to assess modular integration of four social brain subnetworks in 298 ASDs and 348 typically developing (TD) controls.
  • Performed correlation analyses with clinical scores, neurotransmitter systems, transcriptional data, and linear regression for age effects.

Main Results:

  • ASD participants showed increased modular integration of the reward system compared to TD controls.
  • This hyper-integration correlated with social responsiveness scores, 5HT1a and GABAa neurotransmitters, and disrupted transcriptional signatures.
  • The reward system's modular integration abnormality was age-stable and reproducible across datasets.

Conclusions:

  • Identified a symptom-related, neurotransmitter- and transcriptional signature-associated, age-stable, and reproducible reward system hyper-integration in ASD.
  • This finding links to reduced GABAa and serotonin receptor densities, supporting the excitatory-inhibitory imbalance theory in ASD.
  • Provides neuroimaging and molecular evidence for mechanisms underlying social variations in ASD.
