Discussion Overview

The discussion centers around the types of neurons found in the rat's brain, specifically focusing on the nucleus accumbens and their morphological characteristics. Participants seek to identify specific neuron types and their sizes, as well as the overall number of neurons in the rat brain.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant requests a handbook detailing various types of neurons in the rat's brain, expressing difficulty in finding specific resources.
  • Another participant suggests that the request is too general and encourages the original poster to specify their needs, particularly regarding the nucleus accumbens.
  • A later reply specifies interest in morphological differences among neuron types, including Pyramidal, Betz, and Basket neurons, and inquires about their sizes in the nucleus accumbens and amygdala.
  • One participant cites a source indicating that there are approximately 200 million neurons in the rat brain and provides links to additional resources discussing neuron types in the nucleus accumbens, noting that about 95% are GABAergic medium spiny neurons.
  • The same participant mentions the characteristics of GABAergic MSNs and their projections to other areas, but does not clarify the presence of Pyramidal, Betz, or Basket neurons in the nucleus accumbens.

Areas of Agreement / Disagreement

Participants have not reached a consensus on the specific types of neurons present in the nucleus accumbens or their morphological characteristics. The discussion remains unresolved regarding the details of neuron types and sizes.

Contextual Notes

Participants have not fully defined the specific morphological indicators they are interested in, nor have they clarified the conditions under which different neuron types may be present in the nucleus accumbens or amygdala.

Good day guys!

I am looking for the handbook describing the various types of neurons in rat’s brain. Have you got something like this? I tried to find in google this information with these key words:

nissl stain rat brain Accumbens neurons types

and

number of neurons in rat brain

and

handbook of neurobiology rat number of neurons accumbens

but a huge amount of papers appeared and almost none of them contained what I need. Can you help me? :smile:

What is it that you need? You need to be more specific. The "various types of neurons in rat’s brain" is a pretty general statement and can be found in almost any resource you can find in a library and/or online. If you're looking for some more specific information about the nucleus accumbens, as is alluded to by the bolded text in your post, then you need to be more specific in your question.

Ok, I will specify :smile:

As known the neurons differ from each other by their morphological indicators, by various –ergic types and etc. I am looking for their difference from their morphological point of view, are there any Pyramidal neurons, Betz neurons, Basket neurons in nucleus accumbens (and/or in Amygdala)? Also I need to know their sizes :cool:

About 200 million neurons. See table 1: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1567708/

https://en.wikipedia.org/wiki/Nucleus_accumbens:

"Approximately 95% of neurons in the NAcc are GABAergic medium spiny neurons (MSNs) which primarily express either D1-type or D2-type receptors;[12] about 1–2% of the remaining neuronal types are large aspiny cholinergicinterneurons and another 1–2% are GABAergic interneurons.[12] Compared to the GABAergic MSNs in the shell, those in the core have an increased density of dendritic spines, branch segments, and terminal segments. From the core, the neurons project to other sub-cortical areas such as theglobus pallidus and the substantia nigra. GABA is one of the main neurotransmitters in the NAcc, and GABA receptors are also abundant.[19][21] These neurons are also the main projection or output neurons of the nucleus accumbens."
