Summary
The brain utilizes two distinct cortical pathways for decision-making: an automatic parieto-premotor pathway for motor actions and a deliberate temporo-ventrolateral prefrontal pathway for controlled behavior.
Area of Science:
- Neuroscience
- Cognitive Science
- Decision-Making Research
Background:
- Decision-making is crucial for daily life, yet its underlying neural mechanisms are not fully understood.
- Existing research highlights the complexity of how the brain processes choices and generates behavior.
Purpose of the Study:
- To propose and delineate at least two distinct cortical pathways involved in generating decisions.
- To differentiate the roles of these pathways in automatic versus deliberate behavioral choices.
Main Methods:
- Conceptual framework based on extensions of visual processing streams (dorsal and ventral).
- Analysis of distinct neural pathway functions in decision generation and behavioral control.
Main Results:
- Identified two independent cortical pathways for decision-making: the extended dorsal and extended ventral streams.
- The parieto-premotor (extended dorsal) pathway governs autonomous motor action decisions.
- The temporo-ventrolateral prefrontal (extended ventral) pathway manages deliberate decisions and inhibitory control.
Conclusions:
- The brain employs parallel cortical pathways to independently generate decisions for different behavioral contexts.
- Understanding these pathways offers insight into the neural basis of voluntary action and behavioral regulation.

01:20Decision Making
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.

01:37Reason and Intuition
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 brain can only use...
01:14Role of Cerebellum and Prefrontal Cortex in Memory
The cerebellum, while traditionally associated with motor control, also plays a crucial role in memory, particularly in procedural memory, which involves learning motor tasks that become automatic through repetition. For example, studies have shown that when the cerebellum is damaged, individuals or animals lose the ability to learn conditioned motor responses, such as the conditioned eye-blink response in classical conditioning experiments with rabbits. This study demonstrates the cerebellum's...
01:14Decision Making: Traditional Method
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...

01:09Decision Making: P-value Method
The process of hypothesis testing based on the P-value method includes calculating the P- value using the sample data and interpreting it.
First, a specific claim about the population parameter is proposed. The claim is based on the research question and is stated in a simple form. Further, an opposing statement to the claim is also stated. These statements can act as null and alternative hypotheses: a null hypothesis would be a neutral statement while the alternative hypothesis can have a...

01:08Timing and Consequences on Behavior
In operant conditioning, the timing of reinforcement is crucial. For animals like rats and cats, immediate reinforcement (within a few seconds) is much more effective than delayed reinforcement. For example, a food reward for a rat needs to follow within 30 seconds of pressing a bar to be effective.
Humans, however, can respond to delayed reinforcers. We often make decisions between immediate small rewards and delayed larger rewards. This ability to delay gratification is a significant factor...
