Different parts of the brain do different things. right-brain hypothesis with resting state functional connectivity magnetic resonance imaging. The brain can get signals, add them up, and signal back for action in a split second. Nielsen JA, Zielinski BA, Ferguson MA, Lainhart JE, Anderson JS. Alcohol inhibits the generation of the new electrical impulse.American Association of Neurological Surgeons. This binding reaction triggers a new electrical impulse in the receiving cell, and the communication proceeds so that the brain can function normally. The chemicals are called neurotransmitters -they diffuse across the synaptic space between neurons, and bind to specific proteins or receptors on the receiving neuron. The conversion of electrical to chemical signals occurs at the synapse, the connection between two neurons. Because electrical impulses can’t jump from one neuron to the next, electrical impulses are converted to chemical signals. Neurons communicate with each other through the transmission of electrical and chemical signals. The overall “inhibitory” effect of alcohol on the brain is very similar to that produced by other drugs that cause sedation and anesthesia. It also explores some of the diseases and conditions that can affect the CNS. This article discusses the structures that make up the central nervous system and how they function. These electrical impulses carry information that is essential for normal brain function. The CNS is differentiated from the peripheral nervous system, which involves all of the nerves outside of the brain and spinal cord that carry messages to the CNS. It “depresses” or inhibits the function of neurons by reducing their ability to transmit or “fire” electrical impulses. Alcohol acts as a general depressant of the central nervous system.
