Local field potentials (LFPs) are electrical signals recorded from a specific region of the brain or a similar biological tissue. They represent the summed electrical activity of multiple nearby neurons and are primarily associated with the activity of synaptic potentials, rather than the action potentials of individual neurons. LFPs are measured using microelectrodes that are typically inserted into the tissue.
Plateau potentials are a type of sustained depolarization that occurs in certain types of neurons and muscle cells. They are characterized by a prolonged period of depolarization, which makes the cell membrane more positive and can lead to an extended period of action potential firing or muscle contraction. In neurons, plateau potentials are often associated with specific types of excitability and are involved in functions such as rhythm generation in certain circuits (e.g., in neurons of the cardiac pacemaker or certain motor neurons).

Doppler ultrasonography, often simply referred to as Doppler ultrasound, is a medical imaging technique that uses high-frequency sound waves to assess the flow of blood within the body. This technique leverages the Doppler effect, which is the change in frequency or wavelength of sound waves in relation to an observer moving relative to the source of the sound. In Doppler ultrasonography, sound waves are emitted towards moving blood cells.
Medical ultrasound, also known as sonography, is a diagnostic imaging technique that utilizes high-frequency sound waves to create images of internal structures within the body. It is a non-invasive and safe procedure commonly used in various medical fields, including obstetrics, cardiology, and abdominal imaging. ### Key Features of Medical Ultrasound: 1. **How It Works**: A device called a transducer emits high-frequency sound waves that travel through the body and reflect off tissues and organs.
Mode locking is a technique used in lasers to generate short pulses of light (typically in the picosecond to femtosecond range) by forcing different longitudinal modes of the laser cavity to oscillate in phase. In a typical laser, multiple longitudinal modes (which are different frequencies of light that can oscillate in the cavity) can be present, but they may not be in sync with each other. This lack of synchronization results in a continuous wave output.
The Pascal Photocoagulator is a type of laser device used primarily in ophthalmology for the treatment of various eye conditions, particularly those involving the retina. The term "Pascal" refers to the specific technology used in the device, which allows for a more efficient and effective method of laser photocoagulation. Photocoagulation is a procedure that uses laser energy to create small burns in specific areas of the retina.
Functional imaging is a type of medical imaging that provides information about the physiological and functional processes of the body, particularly the brain and other organs. Unlike structural imaging techniques, which focus on the anatomy and structure of tissues—such as X-rays, CT scans, and conventional MRI—functional imaging assesses how various tissues and organs are functioning in real time.
Videokymography (VKG) is a high-speed imaging technique used to visualize and analyze rapid movements, often in the context of biological systems. It combines elements of video recording and kymography to capture dynamic processes. In particular, it is commonly used in the study of vocal fold dynamics in speech and voice research.

Intro to OurBigBook
. Source. We have two killer features:
- topics: topics group articles by different users with the same title, e.g. here is the topic for the "Fundamental Theorem of Calculus" ourbigbook.com/go/topic/fundamental-theorem-of-calculusArticles of different users are sorted by upvote within each article page. This feature is a bit like:
- a Wikipedia where each user can have their own version of each article
- a Q&A website like Stack Overflow, where multiple people can give their views on a given topic, and the best ones are sorted by upvote. Except you don't need to wait for someone to ask first, and any topic goes, no matter how narrow or broad
This feature makes it possible for readers to find better explanations of any topic created by other writers. And it allows writers to create an explanation in a place that readers might actually find it.Figure 1. Screenshot of the "Derivative" topic page.
