Patient discussion about tree

Q. Could i be allergic to trees? I have a lot of olive trees in my neighborhood and I have been told that olive trees are highly allergic.

A. Thanks a lot Brandon. I'll try your tip

Q. if someone is allergic to olive trees, does that mean they are allergic to olive oil as well?

A. I asked him, and he said he has no prob with olive oil.
Dinner was spectacular if i may add :)

However, when the calcium-dependent conductances were removed or the dendritic tree was passive, the cell fired with regular spiking (Fig.
Although there was no significant relationship between gain and morphometrics, the sensitivity had a strong positive correlation with dendritic tree size as measured by the number of terminations (Fig.
Therefore, we tested versions of the computational model that had either subsets of active channels or a passive dendritic tree. With the exception of the relationship between surface area and spike amplitude, we found that simplified models did not reveal important relationships between structure and neuronal function (Table 4).
Neurons in the mammalian brain have morphologically complex and diverse dendritic trees (Purkinje, 1837; Golgi, 1874; Kolliker, 1891; Lorente del No, 1934; Sholl, 1953; Rall, 1964; Segev, 1992; Cajal, 1995).
We found that PMCA2 immunoreactivity (IR) was strongly present on the dendritic tree of the Purkinje cells, while there was only little expression on the axon, the cell soma, and the stem dendrites (Figure 1(a)).
Chronic Inhibition of PMCA2 by Carboxyeosin Induced a Moderate Reduction of Purkinje Cell Dendritic Tree Size.
As shown earlier [5, 6], chronic treatment of cerebellar slice cultures with the mGluR1 agonist DHPG induces a strong reduction of the Purkinje cell dendritic tree. Because PMCA2 is an important regulator of the calcium homeostasis in Purkinje cell dendrites, we studied whether the mGluR1 effect might be mediated by PMCA2.
Dendritic tree width for old relative to young sulcus arbors only approached statistical significance (Figure 4(b), n = 88, P = 0.08).
The cerebellum is considered to have a regular arrangement of neuronal cell types produced by the geometric organization of their somata and dendritic trees. In terms of their dendritic arbors, Purkinje cells (PCs) are the most prominent cell type in the cerebellar cortex.
This was used to efficiently trace dendritic trees labeled with green fluorescent protein (GFP) of L7-tau-GFP mice [15] under control of the L7 promoter [16].
