Inhibitory Neurons: Keeping the Brain’s Traffic in Check
WEBNov 5, 2014 · When activated, inhibitory neurons release the neurotransmitter GABA, which is known to hyperpolarize the postsynaptic neurons, i.e. it makes the membrane potential more negative, making it harder for the neuron to reach the threshold to fire an action potential, thereby causing ‘ inhibition ’. Most often, inhibitory neurons are also called ...
Hubel and Wiesel & the Neural Basis of Visual Perception
WEBOct 29, 2014 · Snap! Crackle! Pop! Those are the sounds that Professors David Hubel and Torsten Wiesel heard in the early 1950s when they recorded from neurons in the visual cortex of a cat, as they moved a bright line across its retina. During their recordings, they noticed a few interesting things: (1) the neurons fired only when the line was in a particular place on the retina, (2) the activity of these ...

Can Neuroscience Explain the Mandela Effect? - Knowing Neurons
WEBFeb 1, 2017 · There are probably several main reasons for the Mandela effect. The first is that a large number of general associations increase the probability that a false memory could emerge. Twin films with similar concepts being released at around the same time were common in the ’90s.

The Brain’s Building Blocks: Of Protons and Voxels
WEBSep 27, 2017 · Re-enter the voxel: A portmanteau of “volume” and “pixel,” the voxel is a 3-dimensional unit that embeds the signals in brain scans. As the MRI machine scans through each dimension of the brain millimeter by millimeter, voxels are formed to enclose the signals created by protons-magnet interactions. The brain as scanned is made of ...
How Binaural Beats Affect Your Brain – and How They Don’t
WEBDec 21, 2017 · Another way binaural beats may influence your brain waves is through phase synchronization. It has been suggested, but not thoroughly tested, that auditory beats increase the synchronization of the phase of brain waves in different brain regions. One study tested the effect of binaural beats on EEG rhythms in epilepsy patients.

How Weight Lifting Gets the Brain in Shape - Knowing Neurons
WEBMar 1, 2022 · Astoundingly, weight training has been shown to protect subregions of the hippocampus —a brain region involved in cognition and long-term memory—from degeneration in populations at risk for Alzheimer’s Disease (e.g., Broadhouse et al, 2020). This neuroprotective effect helps explain the cognitive and memory benefits of …
Excitation and Inhibition: The Yin and Yang of the Brain
WEBJanuary 25, 2017 Joel Frohlich. To make a working nervous system, only two forces are necessary: excitation and inhibition. Excitatory signaling from one cell to the next makes the latter cell more likely to fire. Inhibitory signaling makes the latter cell less likely to fire.
