Microtubule Associated Proteins (MAPs)01:42

Microtubule Associated Proteins (MAPs)

5.8K
Microtubule function and architecture are regulated by an array of specialized proteins called microtubule-associated proteins or MAPs. These proteins are widespread across different organisms and have conserved protein motifs, like the multi-TOG domain for tubulin binding found in the CLASP family of MAPs. Some MAPs are lineage-specific based on their conserved domains. Their functions depend upon the cytoskeletal architecture and cell type they are located within. In-plant cells, a specific...

Plotting of Topographic Maps

483
Topographic maps represent the Earth's surface features using contour lines, which connect points of equal elevation to create a two-dimensional representation of three-dimensional terrain. Creating a topographic map requires a systematic approach.Begin by plotting a scaled grid and marking intersections corresponding to the survey's elevation data points. Assign elevation values at these intersections to build the base map. Next, determine contour levels using a consistent contour interval,...

Coordinates and Map Projections01:29

Coordinates and Map Projections

586
Coordinates and map projections are essential tools in accurately representing the Earth's surface for various applications, ranging from navigation to spatial analysis. The latitude and longitude coordinate system is a universally recognized framework for defining locations. Latitude specifies the distance of a point north or south of the equator, measured in degrees from 0° at the equator to 90° at the poles. Longitude indicates a location's position east or west of the prime meridian,...

Functional Groups02:45

Functional Groups

87.9K
Functional groups are a group of atoms with characteristic properties, which when linked to the carbon skeleton of a molecule, alter the properties of that molecule. For example, the presence of certain functional groups on a molecule will make them hydrophilic, whereas others will make them hydrophobic. These functional groups are an indispensable part of organic chemistry and important components of biological molecules, such as carbohydrates, proteins, lipids, and nucleic acids. Each...

Functionalism

2.5K
William James, John Dewey, and Charles Sanders Peirce were instrumental in founding functional psychology, which draws heavily from Darwin's theory of evolution by natural selection. This theory suggests that individual traits, including behaviors, are adapted to their environments through natural selection. At the heart of functionalism is the concept of adaptation, meaning that a trait enhances an individual's chances of survival and reproduction.
James envisioned psychology's...

Area of Science:

  • Neurosurgery
  • Neurophysiology
  • Epileptology

Background:

  • Brain mapping is essential for successful epilepsy and brain tumor surgeries.
  • Mapping can be performed intraoperatively or extraoperatively.
  • Several factors influence the choice of mapping venue and techniques.

Purpose of the Study:

  • To review neurophysiologic techniques for mapping the cerebral cortex.
  • To discuss the application of these techniques in surgical planning.
  • To cover electrocorticography, cortical somatosensory evoked potentials, and sensorimotor/cognitive function mapping.

Main Methods:

  • Electrocorticography (ECoG) for mapping epileptiform activity and high-frequency activity.
  • Cortical somatosensory evoked potentials (SSEPs) to identify the central sulcus.
  • Direct electrical cortical stimulation to map motor, sensory, and language areas.

Main Results:

  • ECoG aids in planning resection boundaries by identifying epileptogenic zones.
  • SSEPs can precisely locate the primary somatosensory cortex.
  • Direct stimulation effectively maps critical functional cortical regions.

Conclusions:

  • Neurophysiologic mapping techniques are vital for optimizing surgical outcomes in epilepsy and brain tumor patients.
  • The selection of mapping modality depends on surgical goals, patient factors, and desired functional information.
  • Accurate cortical mapping enhances the safety and efficacy of neurosurgical procedures.
