What is oscillatory activity?
Oscillatory activity in groups of neurons generally arises from feedback connections between the neurons that result in the synchronization of their firing patterns. The interaction between neurons can give rise to oscillations at a different frequency than the firing frequency of individual neurons.
How can we prevent El Niño?
- Adaptive social protection programmes for resilience.
- Expanded use of insurance solutions whenever appropriate.
- Protecting dependent populations in institutions: Healthcare, Justice and Education.
Why does the central nervous system communicate with oscillations?
Why then does the central nervous system (CNS) allow the force output to fluctuate? Given that oscillations of neuronal activity are fundamental to the communication between different parts of the CNS (Engel and Fries, 2010), force oscillations may represent one way the brain communicates with the spinal motor neurons.
What is Southern Oscillation explain its significance?
Southern oscillation refers to shifting the surface air pressure between the tropical eastern Pacific and eastern Indian oceans. An important feature connected with the Southern Oscillation (SO) is the El Nino. The changes in pressure conditions are connected to the El Nino.
What does EEG measure?
An EEG is a test that detects abnormalities in your brain waves, or in the electrical activity of your brain. During the procedure, electrodes consisting of small metal discs with thin wires are pasted onto your scalp. The electrodes detect tiny electrical charges that result from the activity of your brain cells.
What is called oscillation?
Oscillation is the repetitive variation, typically in time, of some measure about a central value (often a point of equilibrium) or between two or more different states. The term vibration is precisely used to describe mechanical oscillation.
Can we prevent El Niño and La Niña?
Can we prevent El Niño and La Niña from occurring? No, El Niño and La Niña are naturally occurring climate patterns and humans have no direct ability to influence their onset, intensity, or duration.
What are alpha oscillations?
Alpha waves, or the alpha rhythm, are neural oscillations in the frequency range of 8–12 Hz likely originating from the synchronous and coherent (in phase or constructive) electrical activity of thalamic pacemaker cells in humans. Occipital alpha waves during periods of eyes closed are the strongest EEG brain signals.
What is neuronal activity?
Neuronal activity is an important player during the maturation phase of neuronal development, as it modulates the establishment and refinement of neuronal connections, mainly through its effects on dendrite morphology and synaptic plasticity.
What is El Niño in relation to ocean oscillations?
El Niño–Southern Oscillation (ENSO) is an irregular periodic variation in winds and sea surface temperatures over the tropical eastern Pacific Ocean, affecting the climate of much of the tropics and subtropics. The warming phase of the sea temperature is known as El Niño and the cooling phase as La Niña.
