Association Areas of the Cortex01:21

Association Areas of the Cortex

7.5K
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,...

Lobes of the Cerebrum01:22

Lobes of the Cerebrum

2.6K
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....

Motor and Sensory Areas of the Cortex01:14

Motor and Sensory Areas of the Cortex

5.7K
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....

Functional Brain Systems: Reticular Formation01:13

Functional Brain Systems: Reticular Formation

3.2K
The reticular formation is a complex network of gray and white matter located within the brainstem extending from the medulla to the midbrain.
Within the reticular formation, there are several distinct nuclei that can be classified into three broad categories. The Raphe nuclei are located along the midline of the brainstem. They are primarily known for their role in synthesizing and releasing serotonin, a neurotransmitter involved in regulating mood, appetite, sleep, and circadian rhythms. The...

Somatosensory, Motor, and Association Cortex01:24

Somatosensory, Motor, and Association Cortex

1.5K
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...

Functional Brain Systems: Limbic System01:15

Functional Brain Systems: Limbic System

4.9K
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...

Area of Science:

  • Neuroscience
  • Cognitive Neuroscience

Background:

  • Grid cells, discovered in 2005, are crucial for spatial navigation.
  • They encode position, direction, and distance information in the brain.
  • Grid cells were initially found in the entorhinal cortex (ERC) and adjacent areas.

Purpose of the Study:

  • To provide an overview of grid cell literature in rodents and humans.
  • To explore the unexpected presence of grid-like responses outside the ERC.

Main Methods:

  • Review of existing literature on grid cells.
  • Analysis of functional magnetic resonance imaging (fMRI) studies in humans.

Main Results:

  • Grid-like responses were confirmed in the human ERC using fMRI.
  • Unexpectedly, grid-like fMRI responses were also identified in the orbitofrontal cortex (OFC) and ventromedial prefrontal cortex (vmPFC).

Conclusions:

  • Grid cells play a role in spatial navigation.
  • The function of grid-like responses in the OFC and vmPFC requires further investigation.
