Cocaine Addiction Effects of the Brain: Binge and Craving
Cocaine Addiction Effects of the Brain: Binge and Craving
Cocaine afflicts many individuals and is potently addictive. Originally hailed as a wonder-drug in the late 19th century, cocaine is now considered an illegal substance. Cocaine’s addictive properties can be attributed to changes in the dopamine reward pathway of the Ventral Tegmental Area and Substantia Nigra, Prefrontal Cortex, Dorsal Striatum, Nucleus Accumbens, Amygdala, Globus Pallidus, and Hippocampus. This drug affects the brain in two processes: binge and crave. The binge process highlights cocaine’s ability to block dopamine reuptake from the synapse resulting in hyperstimulation of the postsynaptic neuron in the dopamine reward pathway. The crave process promotes drug-seeking behavior through conditional and contextual cues. Understanding the effects of cocaine in the brain may grant insight in creating future medication and therapies to treat individuals addicted to this drug.
Endochondral Ossification
Endochondral Ossification
This animation describes Endochondral Ossification which is a process of long, short and irregular bone formation using byline template.
Endocrine Gland
Endocrine Gland
This animation describes the formation of endocrine glands starting with the mitosis of mesenchymal tissues, eventually leading to the formation of the secretory portion of the gland by differentiation.
Exocrine Gland
Exocrine Gland
This animation describes the formation of exocrine glands starting with the mitosis of mesenchymal tissues, eventually leading to the formation of the secretory portion of the gland by differentiation.
Formation of Cartilage
Formation of Cartilage
This animation describes the process of cartilage formation starting with separation from the mesenchymal tissue to the formation of an isogenous cell group via mitosis.
Intramembraneous Ossification
Intramembraneous Ossification
This animation describes Intramembranous ossification which is a process of bone formation.
Myeloid Cell Development
Myeloid Cell Development
This animation describes the process of WBC formation from myeloblast.
Optogenetics
Optogenetics
Gene insertion of opsin, light-activated cell-membrane channels, into neurons of interest allows researchers to manipulate light to either excite or inhibit neuronal activity to gain a better understanding of brain function and dysfunction, and explore therapeutic applications.
Red Blood Cell Development
Red Blood Cell Development
This animation describes the formation of red blood cells from proerythroblast.
Synaptic Transmission
Synaptic Transmission
Neurons communicate with each other and relay information to the brain through synapse. Influx of calcium through ion channels acts as a trigger for starting the neurotransmission cascade, which upon reaching action potential, leads to the release of neurotransmitters, propagating the signal from the pre-synaptic membrane to the post-synaptic membrane.
