The prefrontal cortex, mediator of cross-temporal contingencies
Human Neurobiology
|January 1, 1985
Summary
The prefrontal cortex is crucial for organizing goal-directed behaviors over time. It enables actions toward distant goals by supporting short-term memory, preparatory set, and interference control.
Area of Science:
- Neuroscience
- Cognitive Psychology
- Behavioral Science
Background:
- The prefrontal cortex (PFC) is widely recognized for its role in executive functions.
- Organizing complex, goal-directed behaviors over time is a key executive function.
- Understanding the specific contributions of the PFC to temporal organization is essential.
Purpose of the Study:
- To elucidate the role of the prefrontal cortex in the temporal organization of goal-directed behavioral sequences.
- To identify the cognitive functions mediated by the PFC that allow for cross-temporal contingency.
- To explore the functional heterogeneity within the PFC regarding temporal integration.
Main Methods:
- Analysis of lesion effects in the prefrontal cortex.
- Investigation of neuroelectrical phenomena associated with PFC function.
- Measurement of metabolic activity within the prefrontal cortex.
Main Results:
- The prefrontal cortex subserves at least three cognitive functions: short-term memory, preparatory set, and control of interference.
- These functions mediate cross-temporal contingencies, enabling temporally extended behaviors.
- Distinct topographic representations for these functions support the principle of PFC functional heterogeneity.
Conclusions:
- The prefrontal cortex plays a critical role in bridging cross-temporal contingencies.
- Short-term memory, preparatory set, and interference control are key PFC functions for temporal integration.
- Despite functional heterogeneity, these functions collectively support the PFC's supraordinate role in temporal organization of behavior.

01:14Motor and Sensory Areas of the Cortex
The cerebral cortex, the brain's outermost layer, is pivotal in processing complex cognitive tasks, emotions, and various sensory inputs and executing voluntary motor activities. This intricate structure is divided into three primary functional areas: the motor areas, sensory areas, and association areas.
Motor Areas
The motor areas located in the frontal lobe are central to controlling voluntary movements. This region is further subdivided into the primary motor cortex and the premotor cortex.

01:21Association Areas of the Cortex
Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

01:22Lobes of the Cerebrum
The cerebral cortex, a critical structure of the brain, is intricately divided into two hemispheres, each consisting of four distinct lobes: occipital, temporal, frontal, and parietal. These lobes function cooperatively to regulate various cognitive and sensory functions, forming the basis of our complex neural capabilities.
Frontal lobe
The frontal lobes, located behind the forehead, are the command center of our brain, controlling personality, intelligence, and voluntary muscle movements.

01:23Somatosensory, Motor, and Association Cortex
The somatosensory cortex in the parietal lobes is crucial for interpreting sensory data such as touch, temperature, and proprioception. The somatosensory cortex, situated in the parietal lobes, plays a vital role in interpreting sensory information like touch, temperature, and proprioception—awareness of body position. This specialized brain region features an organized structure wherein neurons at the top primarily process sensations originating from the lower body. In contrast, those at the...
01:24Working Memory
Working memory refers to a combination of components, including short-term memory and attention, that allow an individual to hold information temporarily as we perform cognitive tasks. It is an essential cognitive function that enables the execution of complex tasks such as problem-solving, comprehension, and reasoning. Unlike short-term memory, which simply involves the storage of information for a brief period, working memory involves the active manipulation and processing of this information.
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...
