Comments on abstract, title, references

The abstract is well summarized

The title does not reflect the scope of the paper; I suggest "Neuroprotective and Immuno-histochemical effect of ginger in the brain of streptozotocin-induced diabetic rats".

The references are correct and well arranged

Comments on introduction/background

The introduction was well and systematically crafted and well put. Thou the summary part of the paper should be expunged and taken to the conclusion section of the paper.

Comments on methodology

Kindly provide the ethical approval no if the research was approved by any ethical committee.

What is the rationale behind including the control + ginger group?

There was no description of the preparation of the ginger extract. Kindly include it

There was no phytochemical screening. It would be proper we know the exact phytochemicals and the quantities they appear in the extract

Comments on data and results

Kindly explain the rationale behind presenting the immunohistochemical data of the different brain regions of day 8 only? I suggest you include the other two points too

Comments on discussion and conclusions

The discusson is detailed
