When a sound is heard, sound waves may reach the ears at different times. This is referred to as the interaural time difference (ITD). Due to differing lengths and a finite conduction speed within the axons of the delay lines, different coincidence detector neurons will fire when sound comes from different positions along the azimuth.
Molecular neuroscience is a branch of neuroscience that observes concepts in molecular biology applied to the nervous systems of animals. The scope of this subject covers topics such as molecular neuroanatomy, mechanisms of molecular signaling in the nervous system, the effects of genetics and epigenetics on neuronal development, and the molecular basis for neuroplasticity and ...
The term long-term potentiation comes from the fact that this increase in synaptic strength, or potentiation, lasts a very long time compared to other processes that affect synaptic strength. [1] In neuroscience, long-term potentiation (LTP) is a persistent strengthening of synapses based on recent patterns of
Gordon Murray Shepherd (21 July 1933 [1] – 9 June 2022) [2] was an American neuroscientist who carried out basic experimental and computational research on how neurons are organized into microcircuits to carry out the functional operations of the nervous system.
Although systems neuroscience is generally observed in relation to a human’s level of functioning, many studies have been conducted on drosophila, or the small fruit fly, as it is considered to be easier due to the simpler brain structure and more controllable genetic and environmental factors from an experimental standpoint. While there are ...
One of the most noticeable results of further research into neurogenetics is a greater knowledge of gene loci that show linkage to neurological diseases. The table below represents a sampling of specific gene locations identified to play a role in selected neurological diseases based on prevalence in the United States. [9] [10] [11] [12]
Molecular neuroscience is a branch of neuroscience that examines the biology of the nervous system with molecular biology, molecular genetics, protein chemistry and related methodologies (ie. concerning neurotransmitters moving via physiology of synapses etc) Neurochemistry; Nutritional neuroscience; Neuropeptide [ also see Neuropharmacology above]
A bioinformatics network analysis is one approach to this problem. Network analyses methodologies provide a generalized, systems overview of a molecular pathway. One final complication to consider is the comorbidity of neurogenomic genes. Several disorders, especially at the more severe ends of the spectrum tend to be comorbid with each other.
