Stimulants01:29

Stimulants

1.0K
Stimulants are substances that enhance neural activity and elevate dopamine levels in the brain, leading to their highly addictive nature. These drugs include cocaine, amphetamines, MDMA, caffeine, and nicotine, each with distinct mechanisms of action and varied health implications.
Cocaine can be administered via snorting, injection, or smoking. It primarily functions by blocking the reuptake of dopamine, resulting in a euphoric high characterized by an intense sensation of happiness and...

Motor Unit Stimulation01:20

Motor Unit Stimulation

3.8K
When the neuron of a motor unit fires an action potential, it triggers a series of events, leading to a twitch contraction in the muscle fibers. The process of excitation-contraction coupling is crucial in relaying the action potential to the muscle fibers.
The latent period of contraction marks the onset of excitation-contraction coupling, when the action potential propagates across the sarcolemma, preparing the muscle fibers for contraction. As the fibers enter the contraction phase, the...

Muscle Stimulation Frequency01:22

Muscle Stimulation Frequency

4.5K
The contraction strength of muscles is regulated by motor neurons, which modulate the frequency of action potentials dispatched to the motor units based on the body's requirements. This process of varying the muscle stimulation frequency allows muscles to contract with a force that is precisely tailored to the needs of the moment, whether lifting a feather or a heavy box.
Wave summation
At low firing rates, motor neurons induce individual twitch contractions in muscle fibers. These twitches...

Action Potential: Phases of Stimulation01:28

Action Potential: Phases of Stimulation

12.1K
The action potential is a complex electrical event that occurs in excitable cells, such as neurons and muscle cells. It consists of several distinct phases, each with specific characteristics.
Resting Phase:
In this phase, the cell's membrane is at its resting potential, typically around -70 millivolts (mV) for neurons. Inside the cell, there is a higher concentration of potassium ions (K+) and a lower concentration of sodium ions (Na+). Voltage-gated sodium channels are closed, and...

CNS Stimulants: Psychedelic Agents01:22

CNS Stimulants: Psychedelic Agents

794
Hallucinogens, also known as psychedelic drugs, are a class of substances known for their ability to alter perception, cognition, and emotions. Despite their profound effects on the mind, these drugs are non-addictive, setting them apart from many other abused substances. The mechanism of action of these drugs lies in their impact on the 5-HT2A receptor in the brain. Upon activation, this receptor couples to Gq-type G proteins, triggering a cascade that releases intracellular calcium. This...

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids01:24

CNS Stimulants: Cocaine, Amphetamines and Cannabinoids

861
CNS stimulants, such as cocaine, amphetamines, and cannabinoids, have varying structures and mechanisms of action that lead to different therapeutic effects and side effects. Cocaine, with its molecular formula C17H21NO4, is a tropane alkaloid and a tertiary amino compound. It has two chemical forms: the hydrochloride salt and the "freebase." The former is in powder form, while the latter involves removing the hydrochloride salt to create a form that can be smoked. Cocaine exerts its...

Area of Science:

  • Audiology
  • Otoacoustic Emissions
  • Hearing Loss Treatment

Background:

  • Individuals with intact low-frequency hearing and profound high-frequency loss struggle with speech perception, particularly consonants.
  • Difficulty understanding words and hearing in noisy environments is common in this patient group.

Purpose of the Study:

  • To describe the indications and mechanism of electric acoustic stimulation (EAS).
  • To highlight the benefits of EAS for patients with specific hearing loss profiles.

Main Methods:

  • EAS utilizes a cochlear implant electrode array for high-frequency stimulation in the basal cochlear turn.
  • A hearing aid is used concurrently to deliver low-frequency sounds to the apical cochlear turn.

Main Results:

  • EAS addresses the dual needs of preserving low-frequency hearing while restoring high-frequency perception.
  • This hybrid approach aims to improve overall word understanding and hearing in noise.

Conclusions:

  • Electric acoustic stimulation is a viable option for individuals with residual low-frequency hearing and severe-to-profound high-frequency sensorineural hearing loss.
  • EAS offers a combined acoustic and electric stimulation strategy within a single device for enhanced auditory rehabilitation.
