What is the physiological or anatomical difference between place cells and grid cells in the hippocampus?

In the medial temporal lobe,there are specific types of neural cells such as place cells, head-direction cells, grid cells, and boundary vector cells which involved in cognitive map and spatial...

In the taxonomy of memory, which situation or subdivision is related to the spatial memory? Is it necessary to create a new subdivision or not?

In 1987, Squier proposed a taxonomy of memory for the first time and upgrade it in 2004. furthermore in 2010, Michaelian modified it and proposed a new taxonomy for it. But Spatial memory is not...

Why is the tripartite synapse word used commonly in neuroscience ( or neuroglia science)?

there are many types of interneuron especially in dentate gyrus. On the other hand astrocyte and pre and postsynaptic neurons are also existence. I think there is a relationship between all of...

What are the mechanisms for secretion of different gliotransmitters such as glutamate, GABA, and ATP by astrocytes?

Receptors for all major neurotransmitters seem to be present on the astrocytic plasma membrane (Volterra and Meldolesi,2005), and activation of these receptors (because of neural activities) leads...

What is the structure of a neuron-astrocyte network in the dentate gyrus of hippocampus? How many synapses are covered by an astrocyte?

Tripartite synapse was studied and modeled by many researchers such as Pereira, Hydon, Nadkarni, and Postnov, but how is the network really structured? What is the ratio of neurons to astrocytes...

What is your opinion about using "neuroglia-science" or "glia-science" like neuroscience and establishing new specific fields for studying Glia cells?

According to the recent studies about computational power of astrocytes (for review see Min, Rogier 2012) or their role in health and diseases (for review see Philip G. Haydon 2009, Domingues, AMJ...

what kind of adenosine receptor (A2A , A1) is activated in responding to the secretion of ATP by astrocyte?

ATP released from astrocytes is degraded to adenosine and activates presynaptic adenosine A2 or A1 receptors that leads to an increase or decrease in its release probability (Panatier et al. ,...

What is the effect of increasing AMPA receptors on the post synaptic neuron caused by TNF alpha, on astrocytes function in a hippocampal area?

Tumor necrosis factor alpha (TNFa) promotes synaptic scaling and gliotransmission at glutamatergic synapses via complementary post and presynaptic actions (Santello 2012). increasing AMPA...

How can I implicate two sets of differential equations with different time scaling simultaneously (second and millisecond) in Matlab R2013a simulink?

We have two sets of differential equations for neuron dynamics and astrocyte Ca2+ oscillations but with different time scales (Di Garbo 2009). Is it correct that for simulation of these sets...
