... ( Lnenicka, 2020 ; Goel and Dickman, 2021 ) and vertebrates ( Magee and Grienberger, 2020 ). In Hebbian rules of synaptic plasticity, when a presynaptic neuron is not involved in the activity of the post-synaptic neuron, its synaptic transmission decreases. If such a mechanism is present, this lack...

...Carlie A. Muir; Shawn R. Garner; Sashko Damjanovski; Bryan D. Neff ABSTRACT In many fishes, upper thermal tolerance is thought to be limited in part by the heart's ability to meet increased oxygen demands during periods of high temperature. Temperature-dependent plasticity within the cardiovascular...
