How does the sense
of smell work?
Sequence of events:
1.
Smell will enter nose
2.
Olfactory receptor
neurons will detect the
odor.
3.
The OFN’s will send the
information to the
olfactory bulbs.
4.
Olfactory bulbs send
information to the brain
centers, the hippocampus
and the amygdala.
5.
These limbic system
structures influence
emotions and memories
These brain centers are the ones
that perceive odors and access
memories.

Sequence of events:

Neurons can send signals by

If the strength of the LTP
(long-term potential) is
maintained then the memory
can be formed
The brain is a muscle; you can use it or
lose it. The synapses and the pathways
between neurons are used they become
“strengthened or permanently
enhanced”. This is how memory
works.
If the LTP is maintained, then the
longer the memory is maintained.
"LTP is the most recognized cellular
mechanism to explain memory
because it can alter the strength
between brain cell connections. If this
strength is maintained, a memory can
be formed." Dr. William Griffith.

How does the sense of smell
trigger emotions &
memories?
Sequence of events:

Smell enters the nose.
Olfactory bulb processes
smell and sends it to the
amygdala and
hippocampus.
The hippocampus and
amygdala process the
smell.
The smell activates these
memory centers and
stimulates the limbic
system to emit the
memory/emotion.

What are the amygdala
and the hippocampus?
Amygdala:

The center for emotions,
emotional behavior, and
motivation.

The amygdala is connected
to the hippocampus.

A part of the limbic system.
Hippocampus:

Regulates emotions and
stores memory.

Associated mainly with longterm memory.

A part of the limbic system.
Since olfaction is the only sense
that passes through this area of the
brain, this is why the sense of
smell has such success triggering
memories.
The amygdala and the hippocampus
are both memory and emotion centers
in the brain, they are constantly
activating emotions and storing
memories.
These two are so closely linked
because the olfactory bulb, where
the smell is processed, the
amygdala and hippocampus,
where the memories are located,
are close together and closely
connected.
The olfactory bulb has a direct line
with two different memory centers, the
amygdala and the hippocampus. The
olfactory bulb has the best chance to
provoke those memories, leading to
smell being the most powerful sense.
