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...

We describe two methods for visualization and quantification of dendritic arborization in the hippocampus of mouse models: real-time and extended depth of field imaging. While the former method allows sophisticated topographical tracing and quantification of the extent of branching, the latter allows speedy visualization of the dendritic tree.

Transgenic and knockout mouse models of neurological diseases are useful for studying the role of genes in normal and abnormal neurophysiology. This article describes methodologies which can be used to study long-term potentiation, a cellular mechanism which may underlie learning and memory, in transgenic and knockout freely behaving mouse models of neuropathology.
FAQs
The pars opercularis, pars triangularis, and pars orbitalis provide an anatomical framework for examining inferior frontal gyrus function. Studies can analyze this region at the level of its subdivisions while also considering connections with motor, temporal, and parietal networks. This organization helps relate regional findings to speech, cognitive control, and goal-directed behavior without treating the gyrus as functionally uniform.
These connections place inferior frontal gyrus activity within broader networks rather than isolating it as an independent center. Interactions with motor regions are relevant to speech production, while temporal and parietal connections contribute to language-related processing and task-relevant information. Examining these networks helps explain how regional activity supports coordinated behavior.
The region provides a neural focus for studying how the brain inhibits prepotent responses and maintains information relevant to an ongoing task. These functions connect inferior frontal gyrus research with cognitive control, attention, and decision-making. Comparing findings across inhibition and working-memory tasks can clarify how the same frontal territory participates in different forms of goal-directed behavior.
Functional imaging, lesion studies, and electrophysiological methods are central approaches for investigating this region. Together, they support research on language organization, response inhibition, working memory, and decision-making. Using multiple methods allows investigators to examine inferior frontal gyrus involvement from complementary perspectives, linking observed activity or impairment with particular cognitive and behavioral functions.
Research on the region can clarify how language functions are organized across frontal and connected cortical networks. Functional imaging, lesion studies, and electrophysiological methods are used to examine speech selection and production, as well as language-related impairment. These findings contribute to the study of aphasia and help characterize how language organization relates to brain structure and function.
Its involvement in language, attention, cognitive control, and goal-directed behavior makes the region relevant to aphasia, attention disorders, and neurodevelopmental research. Investigators also examine it when studying recovery after brain injury. Such work connects changes in inferior frontal gyrus function with altered behavior and with broader questions about impaired or reorganized brain systems.
