Neostriatum and functions of prefrontal cortex
Acta Neurobiologiae Experimentalis
|January 1, 1972
Summary
The brain
Area of Science:
- Neuroscience
- Neuroanatomy
Background:
- Neostriatal regions receive input from neocortical areas and the dorsal thalamus.
- Neurobehavioral studies show similar results from lesions, stimulations, or recordings in neocortical and associated neostriatal regions.
Purpose of the Study:
- To explore the relationship between the prefrontal cortex and associated neostriatal regions.
- To propose a functional model for corticoneostriatal interactions.
Main Methods:
- Review of anatomical evidence.
- Analysis of neurobehavioral literature, including lesion, stimulation, and recording studies.
Main Results:
- Consistent evidence links specific neocortical areas to restricted neostriatal regions.
- The prefrontal cortex and rostral neostriatum show abundant supporting data for this connection.
- A serial processing paradigm suggests prefrontal cortex influences behavior via the neostriatum.
Conclusions:
- Neostriatal function is likely determined by its cortical and thalamic inputs.
- The prefrontal cortex may act through the neostriatum in mediating certain behavioral tasks.

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,...

01:15Functional 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...
01:22Lobes 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...
01:14Role 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...
