Spatial memory is a type of memory that you don’t hear about very often.
It involves both short-term and long-term memory, and it’s responsible for allowing you to move around your home freely, remember how to get to the grocery store and find things soon after putting them down.
The majority of the research on spatial memory has been conducted on rodents, particularly mice, rats and gerbils.
However, there have been a few more recent investigations that assessed human spatial memory and proved to operate under the same principles identified in rodent spatial memory.
What is spatial memory?
Spatial memory is a type of memory that allows individuals to remember the spatial locations of objects and landmarks.
This form of memory is believed to be mediated by the hippocampus, a region of the brain that is important for learning and memory.
Spatial memory is thought to be involved in a variety of everyday activities such as navigation, object placement, and orienting oneself in space.
Research suggests that damage to the hippocampus can lead to impairments in spatial memory.
For example, patients with hippocampal damage are often unable to remember the location of objects in their environment or develop a sense of direction.
The study of spatial memory has important implications for our understanding of cognitive abilities and how they can be impacted by brain injury.

What are the types of spatial memory?
There are two types of spatial memory: short-term and long-term.
Short-term spatial memory is also known as working memory. This type of memory allows you to remember information for a short period of time, typically less than 30 seconds.
Working memory is believed to be mediated by the prefrontal cortex, a region of the brain responsible for executive functioning skills such as planning and decision making.
Long-term spatial memory is responsible for your ability to remember the layout of your home, the route you take to work, and where you put your keys.
This type of memory is believed to be mediated by the hippocampus, a region of the brain important for learning and memory. Long-term spatial memory can be further divided into two types:
This type of memory allows you to consciously remember the location of objects and landmarks. For example, you might use declarative spatial memory to remember where you parked your car or the route you took to get to work.
This type of memory is more implicit, meaning that you are not consciously aware of the location of objects and landmarks.
For example, you might use procedural spatial memory to remember how to get to the grocery store or how to get home from work.

What is the difference between short-term and long-term spatial memory?
There are a few key differences between short-term and long-term spatial memory.
Short-term spatial memory is believed to be mediated by the prefrontal cortex, while long-term spatial memory is mediated by the hippocampus.
Short-term spatial memory is a conscious process, while long-term spatial memory can be both conscious and unconscious.
Declarative vs. Procedural
Declarative spatial memory is a type of long-term spatial memory that allows you to remember the location of objects and landmarks.
Procedural spatial memory is also a type of long-term spatial memory, but it is more implicit and allows you to remember how to do things, like ride a bike or drive a car.
Short-term spatial memory lasts for less than 30 seconds, while long-term spatial memory can last for days, weeks, or even years.

What does spatial memory help with?
Spatial memory is involved in a variety of everyday activities, such as navigation, object placement, and orienting oneself in space.
This form of memory is also thought to be important for safety, as it helps individuals avoid hazardous areas or objects.
Spatial memory can also be useful for problem solving, as it allows individuals to mentally manipulate objects in order to find a solution.
Researchers believe that spatial memory may be one of the earliest forms of memory to develop, as it is essential for survival.
Studies have shown that damage to areas of the brain responsible for spatial memory can lead to severe deficits in an individual’s ability to navigate their environment.
These findings suggest that spatial memory is a critical cognitive function that plays a vital role in our everyday lives.
Can you improve spatial memory?
There is evidence to suggest that spatial memory can be improved with training.
One study found that adults who underwent eight weeks of working memory training showed improvements in both short-term and long-term spatial memory.
These findings suggest that it is possible to improve spatial memory through cognitive training. However, more research is needed to determine whether these improvements are long-lasting.
While there is no surefire way to prevent memory decline, there are some things you can do to keep your mind sharp as you age.
One of the best ways to protect your memory is to stay physically active and mentally engaged.
Regular exercise has been shown to improve brain health and cognitive function.
Additionally, keeping your mind active by doing things like puzzles, crosswords, and Sudoku can help keep your memory sharp.
If you are concerned about memory loss, speak to your doctor. They can provide you with more information on how to protect your cognitive health as you age.

Spatial memory is a type of long-term memory that allows you to remember the location of objects and landmarks.
This form of memory is thought to be mediated by the hippocampus and is important for navigation, problem solving, and safety.
For example, if you need to find your way back to your hotel after a night out, spatial memory will allow you to retrieve the memories of the route you took and use them to retrace your steps.
Similarly, if you are looking for a specific item in a store, spatial memory will help you to remember where it is located.
Although research on spatial memory is still in its early stages, it is clear that this type of memory plays an important role in our everyday lives.
