How odors are turned into long-term memories
The neuroscientists Dr. Christina Strauch and Dr. Denise Manahan-vaughan from the Ruhruniversidad Bochum have investigated which brain area is responsible for storing odors as long-term memories. Some odors can trigger memories of experiences from years back, sciencedaily.com reported.
The current study shows that the piriform cortex, a part of the olfactory brain, is involved in the process of saving those memories; the mechanism, however, only works in interaction with other brain areas. The findings have been published in the journal Cerebral Cortex.
Christina Strauch, said, “It is known that the piriform cortex is able to temporarily store olfactory memories. We wanted to know, if that applies to longterm memories as well.”

Synaptic plasticity is responsible for the storing of memories in the memory structures of the brain: During that process the communication between neurons is altered by means of a process called synaptic plasticity, so that a memory is created.
Strauch and Manahan-vaughan examined if the piriform cortex of rats is capable of expressing synaptic plasticity and if this change lasts for more than four hours; indicating that longterm memory may have been established. more of it naturally via the sun.
This can also reduce risk of Seasonal Affective Disorder (SAD), according to Saranya Madina, fitness academy trainer at Nuffield Health.
Signal from a higher brain area needed
The scientists wondered whether the piriform cortex needs to be instructed to create a long-term memory.
They then stimulated a higher brain area called the orbitofrontal cortex, which is responsible for the discrimination of sensory experiences.
This time the stimulation of the brain area generated the desired change in the piriform cortex.
Strauch said, “Our study shows that the piriform cortex is indeed able to serve as an archive for long-term memories.
But it needs instruction from the orbitofrontal cortex — a higher brain area — indicating that an event is to be stored as a long-term memory.” and cool-down movements are crucial to keeping the body in shape, especially if you’re exercising in cold conditions.
“Keeping the body loose, limber and warm for a cold weather workout can help prevent painful twists, sprains, tears and other injuries.”
Additionally, you should see a doctor first if you have an existing heart condition.
He said, “Working out in the cold places extra stress on your cardiovascular system.”
Wiener added that it is also important to stay hydrated.
He added, “The body continues to sweat, but that sweat evaporates more quickly, making it seem as though the body is losing less water
“Drinking water before, during and after a workout will help maintain peak performance, protect the body from injury and stay warm.”
Madina added that clothing is also crucial.
She said, “It may seem an obvious one but it’s important for people to dress in layers which are easy to remove when they start to sweat but can also be readded if needed.
“A thin layer of synthetic material (not cotton which stays wet) followed by a fleece or wool layer for insulation followed by a breathable, waterproof layer is advisable.
“Try and keep the hands, feet, head and ears well protected as these areas are most susceptible to frostbite.”
