How well you learn something will inevitably have an impact on how well you recollect it. Follow a healthy diet.
Shortening a lengthy sentence into a much easy-to-remember
acronym can often make that sentence simpler, from the perspective of
remembering and recollecting the original sentence. Similarly, a variety of
other mnemonics are used all around us, and with a fair degree of success as
far as remembering things is concerned. You can come up with different
combinations or 'keywords' using mnemonic methods based on rhyme, alliteration,
sound, song, etc. In addition to the aforementioned methods, here are a few
tips: Concentrate. Or to be more precise, concentrate more while acquiring any
new piece of information. Exercise regularly. Get enough sleep. Stay away from
alcohol and smoking. Keep your mind free of stress. All these things have an
impact on your memory as well as your brain power. Put your memory to test on a
daily basis. Keep your brain active. Try your hand at solving sudoku or any
other 'intelligent' puzzles, games, etc., which require strategic and logical
thinking. Understand your individual memorization process. Are you a person who
remembers things by blindly mugging them up? Or does association or relation
work better for you?
Do you make use of visuals or graphical association Focused In when
storing (or recollecting) a piece of information from your brain? Rather than
trying out hundred different techniques and getting confused, simply find out
what works for you, focus on that, and improve upon it. Many people complain
about difficulty recalling information and lack of concentration while doing
work. However, these issues are a result of unhealthy habits and leading a
stressful life. Poor concentration has also been linked to suboptimal
functioning of the brain. Here are some memory and concentration improvement
tips: Exercise: In order to stimulate brain function and improve blood supply
to the brain, daily exercise such as aerobics or cardio workouts is very
essential. Adequate blood circulation to the brain means, it will function
better. This in turn decreases the likelihood of falling prey to diseases that
cause memory loss. Take Interest: Unless one takes keen interest in activities
that are assigned, how is it possible to remain attentive and concentrate well.
For instance, listening to a lecture without paying much attention can restrict
your ability to recall important points afterwards. Fun Games: There are quite
a few fun games online such as crossword or Sudoku puzzles that are designed to
exercise your brain and improve mental performance.
These online games, also
referred to as brain games help to improve focus and creativity. Identify
Distractions: Many times, children and even adults cannot do their work, if
they are sitting in a noisy environment. To be in focus, the surrounding
environment should be free from distractions. Working on an empty stomach can
also be a great source of distraction, so one should ensure that food cravings
are satisfied, before concentrating on any assignment. Sufficient Sleep: Many
people sleep late at night and get up early in the morning. However, these
improper sleeping patterns can actually disrupt mental focus in all the
activities that are carried out, throughout the day. Yoga: One can
significantly enhance his ability to recall information as well as maximize
concentration by following certain yoga techniques. For instance, pranayama,
also referred to as breathing exercises can help you concentrate and boost
memory. Daily meditation for 15-20 minutes is one of easiest way to control a flickering
mind. Yoga techniques such as 'hatha' yoga can also assist in focusing the mind
and increase problem solving ability. Foods: Following a healthy diet is very
important for optimal brain function. Foods high in omega-3 essential fatty
acids, are considered as 'focus- voluntary motor control of the lower body, as
well as loss of sensations from that point down. A hemisection, however, will
leave spinal cord tracts intact on one side.
The resulting condition would be
hemiplegia on the side of the trauma—one leg would be paralyzed. The sensory
results are more complicated. The ascending tracts in the spinal cord are
segregated between the dorsal column and spinothalamic pathways. This means
that the sensory deficits will be based on the particular sensory information
each pathway conveys. Sensory discrimination between touch and painful stimuli
will illustrate the difference in how these pathways divide these functions. On
the paralyzed leg, a patient will acknowledge painful stimuli, but not fine touch
or proprioceptive sensations. On the functional leg, the opposite is true. The
reason for this is that the dorsal column pathway ascends ipsilateral to the
sensation, so it would be damaged the same way as the lateral corticospinal
tract. The spinothalamic pathway decussates immediately upon entering the
spinal cord and ascends contralateral to the source; it would therefore bypass
the hemisection. The motor system can indicate the loss of input to the ventral
horn in the lumbar enlargement where motor neurons to the leg are found, but
motor function in the trunk is less clear. The left and right anterior
corticospinal tracts are directly adjacent to each other.
The likelihood of
trauma to the spinal cord resulting in a hemisection that affects one anterior
column, but not the other, is very unlikely. Either the axial musculature will
not be affected at all, or there will be bilateral losses in the trunk. Sensory
discrimination can pinpoint the level of damage in the spinal cord. Below the
hemisection, pain stimuli will be perceived in the damaged side, but not fine
touch. The opposite is true on the other side. The pain fibers on the side with
motor function cross the midline in the spinal cord and ascend in the
contralateral lateral column as far as the hemisection. The dorsal column will
be intact ipsilateral to the source on the intact side and reach the brain for
conscious perception. The trauma would be at the level just before sensory
discrimination returns to normal, helping to pinpoint the trauma. Whereas
imaging technology, like magnetic resonance imaging (MRI) or computed
tomography (CT) scanning, could localize the injury as well, nothing more
complicated than a cotton-tipped applicator can localize the damage. That may
be all that is available on the scene when moving the victim requires crucial
decisions be made. The sensory and motor exams assess function related to the
spinal cord and the nerves connected to it. Sensory functions are associated
with the dorsal regions of the spinal cord, whereas motor function is
associated with the ventral side. Localizing damage to the spinal cord is
related to assessments of the peripheral projections mapped to dermatomes.
Sensory tests address the various submodalities of the somatic senses: touch,
temperature, vibration, pain, and proprioception. Results of the subtests can
point to trauma in the spinal cord gray matter, white matter, or even in
connections to the cerebral cortex. Motor tests focus on the function of the
muscles and the connections of the descending motor pathway. Muscle tone and
strength are tested for upper and lower extremities. Input to the muscles comes
from the descending cortical input of upper motor neurons and the direct
innervation of lower motor neurons. Reflexes can either be based on deep
stimulation of tendons or superficial stimulation of the skin. The presence of
reflexive contractions helps to differentiate motor disorders between the upper
and lower motor neurons. The specific signs associated with motor disorders can
establish the difference further, based on the type of paralysis, the state of
muscle tone, and specific indicators such as pronator drift or the Babinski
sign. The role of the cerebellum is a subject of debate. There is an obvious
connection to motor function based on the clinical implications of cerebellar
damage. There is also strong evidence of the cerebellar role in procedural
memory. The two are not incompatible; in fact, procedural memory is motor
memory, such as learning to ride a bicycle. Significant work has been performed
to describe the connections within the cerebellum that result in learning.
A
model for this learning is classical conditioning, as shown by the famous dogs
from the physiologist Ivan Pavlov’s work. This classical conditioning, which
can be related to motor learning, fits with the neural connections of the
cerebellum. The cerebellum is 10 percent of the mass of the brain and has
varied functions that all point to a role in the motor system. The cerebellum
is located in apposition to the dorsal surface of the brain stem, centered on
the pons. The name of the pons is derived from its connection to the
cerebellum. The word means “bridge” and refers to the thick bundle of
myelinated axons that form a bulge on its ventral surface. Those fibers are
axons that project from the gray matter of the pons into the contralateral
cerebellar cortex. These fibers make up the middle cerebellar peduncle (MCP)
and are the major physical connection of the cerebellum to the brain stem
([link]). Two other white matter bundles connect the cerebellum to the other
regions of the brain stem. The superior cerebellar peduncle is the connection
of the cerebellum to the midbrain and forebrain. The inferior cerebellar
peduncle is the connection to the medulla. The connections to the cerebellum
are the three cerebellar peduncles, which are close to each other. The ICP
arises from the medulla—specifically from the inferior olive, which is visible
as a bulge on the ventral surface of the brain stem.
