Decision Making01:20

Decision Making

391
Decision-making is a fundamental cognitive process that involves evaluating alternatives and selecting among them. This process can range from simple choices, such as deciding what to wear, to complex decisions, like choosing a major in college or a career path. The complexity of the decision often dictates the approach we use, which can be broadly categorized into two types: automatic and controlled decision-making.
Automatic decision-making is fast, intuitive, and relies on gut feelings...

Reason and Intuition01:37

Reason and Intuition

7.1K
The human brain processes information for decision-making using one of two routes: an intuitive system and a rational system (Epstein, 1994; popularized by Kahneman, 2011 as System 1 and System 2, respectively). The intuitive system is quick, impulsive, and operates with minimal effort, relying on emotions or habits to provide cues for what to do next, while the rational system is logical, analytical, deliberate, and methodical. Research in neuropsychology suggests that the...

Drugs Affecting GI Tract Motility: Serotonin Receptor Agonists

538
Serotonin, a crucial neurotransmitter synthesized by enterochromaffin cells, plays a cardinal role in regulating gastrointestinal (GI) motility. With over 90% of the body's total serotonin in the GI tract, its influence on digestive processes is profound. Serotonin is swiftly released upon various stimuli, such as food boluses or certain drugs, triggering intrinsic sensory neurons in the myenteric plexus and extrinsic vagal and spinal sensory neurons. This leads to the activation of the...

Decision Making: Traditional Method01:14

Decision Making: Traditional Method

4.6K
The process of hypothesis testing based on the traditional method includes calculating the critical value, testing the value of the test statistic using the sample data, and interpreting these values.
First, a specific claim about the population parameter is decided based on the research question and is stated in a simple form. Further, an opposing statement to this claim is also stated. These statements can act as null and alternative hypotheses, out of which a null hypothesis would be a...

Role of Emotions in Social Life01:01

Role of Emotions in Social Life

151
Emotions play a fundamental role in shaping human experience and interactions. The absence of emotions would render life incomplete and fail to capture the essence of human nature. In social psychology, feelings and moods have been extensively studied due to their profound impact on social life and interpersonal relationships. These affective states influence decision-making, behavior, and social perceptions, making them integral to understanding human interactions.Emotions and Social...

Human Genetics01:28

Human Genetics

938
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...

Area of Science:

  • Neuroscience
  • Behavioral Science

Background:

  • Adaptive decision making is critical for survival and goal achievement.
  • The neural mechanisms underlying the alignment of actions with goals are not fully understood.

Purpose of the Study:

  • To investigate the role of dorsal raphe serotonin neurons in adaptive decision making.
  • To determine if serotonin neuron activity is necessary for actions to reflect current goal values.

Main Methods:

  • Utilized optogenetic manipulation of dorsal raphe serotonin neurons in a decision-making task.
  • Measured behavioral choices and correlated them with neuronal activity.

Main Results:

  • Activity in dorsal raphe serotonin neurons was essential for adaptive decision making.
  • Inhibition of these neurons impaired the ability of actions to align with goal values.

Conclusions:

  • Dorsal raphe serotonin neuron activity plays a vital role in adaptive decision making.
  • These neurons facilitate the reflection of current goal values in behavioral choices.
