Source: James W Bonz, MD, Emergency Medicine, Yale School of Medicine, New Haven, Connecticut, USA Lateral canthotomy is a potentially eyesight-saving procedure when performed emergently for an orbital compartment syndrome. An orbital compartment syndrome results from a buildup of pressure behind the eye; as pressure mounts, both the optic nerve and its vascular supply are compressed, rapidly leading to nerve damage and blindness if the pressure is not quickly relieved. The medial and lateral...

The present work provides a comprehensive set of guidelines for manually tracing the medial temporal lobe (MTL) structures. This protocol can be applied to research involving structural and/or combined structural-functional magnetic resonance imaging (MRI) investigations of the MTL, in both healthy and clinical groups.

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.

It brings visual, auditory, and somatosensory signals into a shared representation rather than treating each input independently. This integration links events in the external environment with information about the body, allowing the brain to organize spatial relationships, interpret meaning, and select goal-directed actions. The process helps explain how perception can guide behavior in changing situations.
Body-state information gives sensory events a reference point for interpreting location, action, and self-related experience. Within the inferior parietal lobe, signals about the body can be combined with external sensory inputs to support spatial representations and action planning. This relationship is also relevant to research on self-other representation, where investigators examine how cognition distinguishes personal experience from information about others.
Its activity does not operate in isolation. The inferior parietal lobe interacts with distributed attention networks to help select and organize behaviorally relevant information, while its interactions with language networks contribute to the interpretation of meaning. Studying these relationships helps neuroscience explain how sensory integration supports both goal-directed behavior and higher-level communication.
Inferior parietal lobe processing contributes to several functions that require integrated information rather than a single sensory operation. These include perception, attention, language, tool use, numerical processing, empathy, and self-other representation. Examining this range of functions shows why the region is associated with complex cognition and why different patterns of disruption can produce selective deficits.
Neuroscientists study the region through neuroimaging, electrophysiology, and lesion analysis. Neuroimaging examines activity in relation to cognitive tasks, electrophysiology measures neural activity, and lesion analysis connects damage with changes in cognition or behavior. Using these approaches provides complementary evidence about regional function, network interactions, and the consequences of impaired parietal processing.
Studies can ask how sensory information becomes a spatial representation, how attention selects relevant stimuli, or how language-related activity contributes to meaning. Researchers also investigate tool use, numerical processing, empathy, and self-other representation. These applications connect regional activity with broader questions about how distributed neural systems produce perception, planning, communication, and social cognition.
Lesion analysis can reveal which cognitive and behavioral functions depend on intact parietal processing by relating damage to selective impairments. In the inferior parietal lobe, this approach can clarify disruptions involving perception, attention, language, or goal-directed behavior. Because deficits may be selective rather than global, lesion findings help distinguish specialized contributions within complex cognitive networks.
