Behavioral plasticity is the change in an organism's behavior that results from exposure to stimuli, such as changing environmental conditions. [1] Behavior can change more rapidly in response to changes in internal or external stimuli than is the case for most morphological traits and many physiological traits.
Phenotypic plasticity refers to some of the changes in an organism's behavior, morphology and physiology in response to a unique environment. [1] [2] Fundamental to the way in which organisms cope with environmental variation, phenotypic plasticity encompasses all types of environmentally induced changes (e.g. morphological, physiological, behavioural, phenological) that may or may not be ...
Behavioral plasticity, change in an organism's behavior in response to exposure to stimuli; Neuroplasticity, in neuroscience, how entire brain structures, and the brain itself, can change as a result of experience Synaptic plasticity, the property of a neuron or synapse to change its internal parameters in response to its history
Some of the most pervading examples of this can be seen through the development of the visual cortex in addition to the acquisition of language as a result of developmental plasticity during the critical period. [9] [33] A lesser known example, however, remains the critical development of respiratory control during developmental periods. At ...
Many behaviors that are commonly thought of as spiteful are actually better explained as being selfish, that is benefiting the actor and harming the recipient, and true spiteful behaviors are rare in the animal kingdom. An example of spite is the sterile soldiers of the polyembryonic parasitoid wasp. A female wasp lays a male and a female egg ...
Activity-dependent plasticity is a form of functional and structural neuroplasticity that arises from the use of cognitive functions and personal experience. [1] Hence, it is the biological basis for learning and the formation of new memories.
Two molecular mechanisms for synaptic plasticity involve the NMDA and AMPA glutamate receptors. Opening of NMDA channels (which relates to the level of cellular depolarization) leads to a rise in post-synaptic Ca 2+ concentration and this has been linked to long-term potentiation, LTP (as well as to protein kinase activation); strong depolarization of the post-synaptic cell completely ...
If the organism moves towards the stimulus the taxis are positive, while if it moves away the taxis are negative. For example, flagellate protozoans of the genus Euglena move towards a light source. This reaction or behavior is called positive phototaxis since phototaxis refers to a response to light and the organism is moving towards the stimulus.
