Summary
Downing and Peelen view the Extrastriate Body Area (EBA) and Fusiform Body Area (FBA) as isolated. However, evidence suggests these visual areas are influenced by higher-level feedback within a predictive coding framework.
Area of Science:
- Neuroscience
- Cognitive Neuroscience
- Visual Perception
Background:
- The Extrastriate Body Area (EBA) and Fusiform Body Area (FBA) are key visual processing regions.
- Previous models proposed limited top-down influence on EBA and FBA, primarily attentional modulation.
Purpose of the Study:
- To evaluate the impenetrability of EBA and FBA within a predictive coding framework.
- To investigate the influence of higher-level cortical areas on EBA and FBA responses.
Main Methods:
- Commentary and theoretical evaluation of existing research.
- Discussion of functional magnetic resonance imaging (fMRI) adaptation evidence.
Main Results:
- fMRI-adaptation effects in occipitotemporal cortex, including EBA and FBA, support top-down modulation.
- Evidence indicates interactive feedback within a hierarchical network shapes responses in EBA and FBA.
Conclusions:
- The EBA and FBA are not impenetrable systems.
- Higher-level cognitive processes dynamically modulate activity in body-selective visual areas through feedback mechanisms.

01:24Facial Feedback Hypothesis
956
Charles Darwin proposed that facial expressions are an evolutionary adaptation for communication. He argued that these expressions are not influenced by culture but are universal across species. For example, a snarling expression with exposed teeth signals a threat in many animals, including humans. Darwin also suggested that displaying an emotion can intensify the feeling. Smiling, for example, could enhance one's sense of happiness. This idea laid the foundation for understanding the role...

01:21Association Areas of the Cortex
10.2K
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,...

01:01Neuroplasticity
2.6K
Neuroplasticity reflects the brain's remarkable capacity to adapt and evolve, responding dynamically to learning, experiences, or injury by reorganizing its neural circuitry. This reorganization involves creating new neural connections and refining old ones through a series of biological processes that contribute to the brain's lifelong development and adaptability.

01:24Effects of feedback
1.1K
Feedback in control systems plays a critical role in shaping various operational parameters, extending beyond simple error reduction to influence stability, bandwidth, gain, impedance, and sensitivity. Understanding these effects requires examining a basic feedback system characterized by defined input, output, error, and feedback signals.
Feedback significantly modifies the gain of a control system. The gain of a system without feedback is altered by a factor of one plus GH, where G represents...

01:14Motor and Sensory Areas of the Cortex
8.1K
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....
