It is true that some of us get more forgetful as we age. It may take longer to learn new things, remember certain words, or find our glasses. These changes are often signs of forgetfulness. Brain scientists believe that the effects of normal aging on memory may result from the subtly changing environment within the brain. With aging, the brain seems to lose cells in areas that produce important neurotransmitters, upsetting the brain’s delicate balance of these chemical messengers. Other changes occur in the brain’s white matter, which is made up of nerve cell fibers, the “telephone cables” of brain cells through which communication with other cells takes place. Just how these changes affect memory is not entirely clear, but it may be that they decrease the efficiency of cell-to-cell communication. What the scientist knows is as we get older, our capability to lay down fresh memories may be affected, making it more difficult to learn new things. It’s not so much that we forget more easily, but that we may take longer to learn the information in the first place A lot of studies have been made in different substance for its potential property on enhancing memory and cognition. Docosahexaenoic acid is one of them. DHA is the most abundant omega-3 fatty acid in the brain. DHA is believe that it could maintain memory and support overall cognitive health. A carotenoid namely fucoxanthin increase the amount DHA in the biological system without intake of fish oil supplementation. It is also consider that low carotenoid levels could play a role in cognitive impairment. Phytochemicals such as antioxidants polyphenolic compounds flavonoids occur all over in foods of plant origin like fruits and vegetable, carotenoids, vitamin E and vitamin C have also a possible in improving age-related neurological dysfunction. These substances could also be found in marine algae and other marine organism. DHA is mostly found in the fish oil but the DHA originates from the photosynthetic and heterotrophic microalgae and macroalgae that the fish ate and other marine creature. Phytochemical such as flavonoids is found also in algae. Knowing about this there could be a possibility for its memory and cognitive enhancing property. Eating seaweeds could have its benefits. It is time to get to know the seaweeds known in the Filipino tables which are Caulerpa lentillifera (lato), Kappaphycus alvarezii (guso) and lukot although everyone calls it a 'seaweed', “lukot” is anything but a the 'secretions' of the creature dongsul/Sea Hare (Dolabella auricularia) and it is not an algae but it eats algae. With all this information there could be a possibility for its memory and cognitive enhancing property. Thus this study is to be conducted.

Objective of the Study
This study aims to determine the memory and cognitive enhancing properties of Caulerpa Lentillifera (lato), Kappaphycus alvarezii (guso) and and egg mass of Sea Hare(Dolabella auricularia) on mature albino mice.
1. To determine the average time at which the mice were able to complete the task after the allotted period for the consumption of the pigeon pellets, Caulerpa Lentillifera (lato), Kappaphycus alvarezii (guso) and egg mass of Sea Hare(Dolabella auricularia).
2. To compare which of the treatment Caulerpa Lentillifera (lato), Kappaphycus alvarezii (guso) and “lukot” egg mass of Sea Hare(Dolabella auricularia) have more cognitive and memory enhancing property.
Significance of the Study
The importance of the study is to help us reveal the potential cognitive and memory enhancing property...
