Summary
Architectural ranking impacts perception, with early brain responses differentiating building types. The hippocampus is crucial for later processing of high-ranking buildings, particularly in healthy individuals.
Area of Science:
- Neuroscience
- Cognitive Psychology
- Architectural Psychology
Background:
- Architectural theories propose that high-ranking buildings elicit stronger cognitive responses than low-ranking ones.
- The role of the hippocampus in processing architectural aesthetics remains largely unexplored.
Purpose of the Study:
- To investigate the neural processing of architectural ranking using event-related potentials (ERPs).
- To determine the hippocampus's contribution to categorizing buildings based on their architectural rank.
Main Methods:
- Utilized ERPs during a visual object categorization task.
- Compared brain responses in healthy subjects and patients with temporal lobe epilepsy (TLE), with and without hippocampal sclerosis.
Main Results:
- Early negative potentials (200–400 ms) distinguished high- and low-ranking buildings across all participant groups.
- Late positive potentials (400–600 ms) showed higher amplitude for high-ranking buildings in healthy subjects and TLE patients without hippocampal sclerosis, but not in those with it.
Conclusions:
- Architectural rank processing involves early visual selection and later post-model selection stages.
- The hippocampus plays a critical role in the later stages of visual object categorization related to architectural ranking.

01:19Role of Hippocampus in Memory
The hippocampus, a critical brain structure, plays an essential role in memory processing, particularly in the formation and retrieval of memory. This small, seahorse-shaped region is located within the medial temporal lobe, with one hippocampus in each brain hemisphere. Experimental studies involving lesions in the hippocampi of rats have demonstrated significant impairments in tasks such as object recognition and maze navigation, indicating the hippocampus involvement in both recognition and...
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...
01:25Olfaction
The sense of smell is achieved through the activities of the olfactory system. It starts when an airborne odorant enters the nasal cavity and reaches olfactory epithelium (OE). The OE is protected by a thin layer of mucus, which also serves the purpose of dissolving more complex compounds into simpler chemical odorants. The size of the OE and the density of sensory neurons varies among species; in humans, the OE is only about 9-10 cm2.

01:23Storage
A schema is a mental framework that helps individuals organize and interpret information. Schemata, formed from previous experiences, influence how we process new information: how we encode it, the inferences we make, and how we retrieve it. For instance, a schema for what a typical classroom looks like might include desks, a teacher's desk, a whiteboard, and students in such an environment. This expectation helps us quickly understand and navigate new classrooms without needing to analyze each...
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,...
