Prasagraj: In the background of the fact that the Brain of Indian tropical birds, Coracias Benghalensis, commonly known as Indian rollers or ‘Neelkanth “, are quite identical to humans, experts from the Zoology Neurobiology Laboratory, University of Allahabad have for the first time revealing that during the mating season , the learning and the memory of the bird was enhanced and leading to identifying the perfect partner for behavior and marriage, the construction of nests, territorial tagging and parental care.
This study, led by Prof.
Kp Singh and his colleague Kirti Ojha, has been published in international journals ” Zoölogy “(published by Elsevier) which has a high impact factor.” This bird has two reproduction phases, breeding (May to July when they put the eggs and hatch it) and non-breeding (the rest of the month a year).
During the marriage season, male birds feature dramatic dance dances in the air that are blessed with acrobatic performances to attract women by flying high in the air with stretched wings and rolling and tend to fall in a circular pattern and hustle and bustle sound.
These strange behaviors are not carried out during the non-breeding phase and resting in bird life, “explained Prof.
Singh.
Researchers connect this phenomenon with the learning and memory center of the bird brain, the hippocampal complex, which is similar to hippocampus mammals including humans.
Further revealed that during The phase of life breeding, the volume of hippocampus increases, additional neuron connections or circuits (ddrit) of various types of neurons developed and most importantly “dendritic thorns” increased substantially.
“This ‘dendritic’ is scientifically called the ‘memory molecule’.
It is assumed that all brain connections activate during the mating season, but major changes are found in the hippocampus structure and function because the learning capacity increases a lot of folds and leads into permanent memory in the form of ‘sexual printing’ for the selection of partners and marriages, “said Prof.
Singh.
conducted in the number of birds at least after permission from the higher parties from the Ministry of Forestry, Lucknow and approval of the institutional animal ethics committee on the AU.
“We must understand that because the bird’s hippocampal complex is analogous to the human brain, therefore it is conserved that during human pregnancy, change Substantive in the brain of the mother expected, “explained Prof.
Singh.
At present, Prof Singh’s laboratory is exploring the complex ambiguity of prenatal learning or the potential to learn the fetal brain in the mother’s womb.
