When triggered by an odor, rapid changes in membrane voltage and intracellular calcium ion levels occur in nematode olfactory neurons, causing membrane voltage sensors and calcium ion sensors to ...

Brain functions stem from and rely on electrical signals created and propagated by neurons. As such, scientists measure electrical signals to study neuronal function at both single-cell and systemic ...

Experimental setup for observational fear testing and calcium imaging in observer mice. The observer mouse witnesses the demonstrator mouse receiving electric shocks, enabling the assessment of ...

Understanding how the human brain stores information and later uses it to complete various tasks has been a long-standing goal of neuroscience and psychology research. Past studies have identified ...

At the core of neuronal communication lie action potentials, brief, rapid electrical impulses that travel down the axon to transmit information for brain function. Abnormalities in neuron firing are ...

I still vividly remember the first time we observed neurons responding not to audible sound, but to concentrated, precisely calibrated ultrasonic pulses. On the screen in front of us, calcium signals ...
