\section{Neuronale Kodierung}
|
||||||
|
In sensorischen Systemen kodieren Populationen von Neuronen mit ihrer
|
||||||
|
Aktivit\"at Eigenschaften von sensorischen Stimuli. z.B. im visuellen
|
||||||
|
Kortex V1 die Orientierung eines Balkens. Traditionell wird die
|
||||||
|
Antwort der Neurone f\"ur verschiedene Stimuli (z.B. verschiedene
|
||||||
|
Orientierungen des Balkens) gemessen. Die mittlere Antwort der Neurone
|
||||||
|
als Funktion eines Stimulusparameters ist dann die ``Tuning-curve''
|
||||||
|
(z.B. Feuerrate als Funktion des Orientierungswinkels).
|
||||||
|
|
||||||
|
\begin{figure}[tp]

\includegraphics[width=1\textwidth]{mlecoding}

||||||

\caption{\label{mlecodingfig} Maximum Likelihood Sch\"atzung eines
|
||||||
|
Stimulusparameters aus der Aktivit\"at einer Population von
|
||||||
|
Neuronen. Oben: Die Tuning-Kurve eines einzelnen Neurons in
|
||||||
|
Abh\"angigkeit von der Orientierung eines Balkens. Der Stimulus
|
||||||
|
der die st\"akste Aktivit\"at in diesem Neuron hervorruft ist ein
|
||||||
|
senkrechter Balken (Pfeil, $\phi_i=90$\,\degree. Die rote Fl\"ache
|
||||||
|
deutet die Variabilit\"at $p(r)$ der Aktivit\"at $r$ um die
|
||||||
|
Tuning-Kurve herum an. Mitte: Jedes Neuron in der Population hat
|
||||||
|
eine andere bevorzugte Orientierung des Stimulus (farbige Linien).
|
||||||
|
Ein Stimulus einer bestimmten Orientierung aktiviert die Neurone
|
||||||
|
in spezifischer Weise (Punkte). Unten: Die Log-Likelihood dieser
|
||||||
|
Aktivit\"aten wir maximal in der N\"ahe der wahren Orientierung
|
||||||
|
des Stimulus.}
|
||||||
|
\end{figure}
|
||||||
|
|
||||||
|
Das Gehirn ist aber mit dem umgekehrten Problem konfrontiert: gegeben
|
||||||
|
eine bestimmte Aktivit\"at der Neurone in der Population, was war der
|
||||||
|
Stimulus (die Orientierung des Balkens)? Eine m\"ogliche Antwort ist
|
||||||
|
im Sinne von Maximum-Likelihood: es war der Stimulus f\"ur den das
|
||||||
|
Aktivit\"atsmuster am wahrscheinlichsten ist.
|
||||||
|
|
||||||
|
Bleiben wir mit einem Beispiel bei den orientierungssensitiven Zellen
|
||||||
|
des V1. Das Tuning $\Omega_i(\phi)$ der Zellen $i$ auf ihre bevorzugte
|
||||||
|
Orientierung $\phi_i$ l\"asst sich gut mit einer van-Mises Funktion
|
||||||
|
(entspricht der Gaussfunktion auf einer zyklischen x-Achse)
|
||||||
|
beschreiben (\figref{mlecodingfig}):
|
||||||
|
\[ \Omega_i(\phi) = c \cdot e^{\cos(2(\phi-\phi_i))} \quad , \quad c
|
||||||
|
\in \reZ \]
|
||||||
|
Die Aktivit\"at der Neurone approximieren wir hier mit einer
|
||||||
|
Normalverteilung um die Tuning-Kurve mit Standardabweichung
|
||||||
|
$\sigma=\Omega/4$ proportional zu $\Omega$, so dass die
|
||||||
|
Wahrscheinlichkeit $p_i(r|\phi)$ des $i$-ten Neurons die Aktivit\"at $r$ zu
|
||||||
|
haben, wenn ein Stimulus mit Orientierung $\phi$ anliegt, gegeben ist durch
|
||||||
|
\[ p_i(r|\phi) = \frac{1}{\sqrt{2\pi}\Omega_i(\phi)/4} e^{-\frac{1}{2}\left(\frac{r-\Omega_i(\phi)}{\Omega_i(\phi)/4}\right)^2} \; . \]
|
||||||
|
Die Log-Likelihood der Stimulusorientierung $\phi$ gegeben die
|
||||||
|
Aktivit\"aten $r_1$, $r_2$, ... $r_n$ ist damit
|
||||||
|
\[ {\cal L}(\phi|r_1, r_2, \ldots r_n) = \sum_{i=1}^n \log p_i(r_i|\phi) \]
